Explain what is wrong with each incorrect statement. Explain when chemical reactions continue and when they stop. A. A chemical reaction proceeds until the enzyme molecules are all consumed. B. A chemical reaction proceeds until the substrate molecules are all consumed. C. A chemical reaction proceeds until equilibrium is established. D. A chemical reaction proceeds until all the product molecules are removed.
: B and C are correct as written, but B requires some clarification. A is incorrect because enzyme molecules are not consumed in chemical reactions and will continue to be active until acted upon by environmental conditions (temperature, pH, or modifiers). B is correct only when the product is removed from the system. If the product remains, the enzyme will reach equilibrium where the ratio of substrate to product is constant (Correct Answer C). In D, if the product of the reaction is removed, the reaction would continue to proceed to form new product (assuming enzymes and substrates are available). Chemical reactions continue if conditions are favorable, including presence of substrate and enzyme and fairly constant temperature and pH.

Viruses can only survive and reproduce inside a host cell. Bacteria are susceptible to antibiotics. Viruses are treated with antiviral drugs. See Table 24.1 in the chapter. Section Title: Pathogens of the Human Body Learning Outcome: 24.3
: Level II: Reviewing Concepts (Bloom's Taxonomy: Knowledge) 86) Describe the physical protection afforded by the cerebrospinal fluid.
: Because the brain floats on CSF there is less weight and, therefore, less pressure on the blood vessels and nerves attached to the CNS. The fluid also pads the brain so it is less likely to hit the cranium and risk bruising when there is a blow to the head. Section Title: Anatomy of the Nervous System Learning Outcome: 9.5
: Level III: Problem Solving (Bloom's Taxonomy: Application) 127) When the kidney goes into failure, one of the signs that doctors will see is that red blood cells will crenate (shrivel up). Why does this happen in kidney failure? What process is occurring to the blood cells?
: Because the kidney is failing to filter particles out of the blood effectively, the plasma becomes hypertonic or hyperosmotic in comparison to the intracellular compartment of the blood cell. Since the cell membrane is impermeable to the ions, but permeable to water, water will leave the cell to try to balance the tonicity and osmolarity with the plasma and in the process the cell will shrink.

: Level II: Reviewing Concepts (Bloom's Taxonomy: Analysis) 102) By binding to the Ca2+ channel proteins, drugs known as calcium channel blockers have two main effects. Name them. Why are some cells unaffected by these drugs?
: Binding to calcium channels makes them less likely to open, effectively blocking the normal inward calcium current that would result from neural or endocrine stimulation. This causes vasodilation and a decrease in heart rate. Insensitive tissues have a different subtype of calcium channel. Section Title: Cardiovascular Disease Learning Outcome: 15.5
: Level IV: Quantitative Problems (Bloom's Taxonomy: Application) 229) Explain the roles that the AMPA and NMDA receptors play in long-term potentiation.
: Both AMPA and NMDA receptors are located on the postsynaptic cells (dendrites) and require binding of the excitatory neurotransmitter glutamate for activation. When glutamate binds to the AMPA receptor, the channel opens and Na enters the cell. This causes depolarization of the immediate postsynaptic cell or dendrite. This depolarization causes Mg2+ ions to be "kicked out" of the NMDA receptor channel; hence, Mg2+ is no longer acting as a channel blocker. If at the same time glutamate is bound to the NMDA receptor then the channel gate is open and Ca2+ enters the cell. The entry of Ca2+ triggers 2nd messenger pathways that results in an increase in the number of glutamate receptors inserted into the post-synaptic membrane. This increases the probability of an increase in the postsynaptic response or depolarization to glutamate that is referred to as long-term potentiation.

: Level II: Reviewing Concepts (Bloom's Taxonomy: Comprehension) 96) Define implicit and explicit memory.
: Both are a type of long-term memory. Implicit or reflexive memory is automatic and does not require conscious effort. Examples are tasks that primarily involve motor skills such as writing or throwing a ball and the memory tasks typically stored at in large part in the cerebellum and the amygdala. Explicit or declarative memory requires conscious attention, using higher-level thinking skills. These memories can be communicated. Section Title: Brain Function Learning Outcome: 9.17

: Level II: Reviewing Concepts (Bloom's Taxonomy: Comprehension) 185) Compare and contrast Schwann cells and oligodendrocytes.
: Both insulate axons by creating myelin. Schwann cells, found in the PNS, are associated with a single axon. One axon may have many Schwann cells wrapped around it leaving small gaps of unmyelinated areas called nodes of Ranvier. Oligodendrocytes are found in the CNS and form myelin around portions of several axons. Section Title: Cells of the Nervous System Learning Outcome: 8.1
: Level II: Reviewing Concepts (Bloom's Taxonomy: Application) 98) Compare and contrast facilitated diffusion and active transport.

: Level II: Reviewing Concepts (Bloom's Taxonomy: Application) 97) Compare and contrast the effectiveness of the immune response to bacterial and viral infection.
: Both pathogens are foreign and thus have antigens, therefore they each stimulate both branches of the immune response. The humoral response is more effective at eliminating bacterial infections than viral infections because bacteria typically do not have self antigens. The cell-mediated immune response is more effective at eliminating viral infections than bacterial, because viruses infect and therefore alter self cells, and it is altered self cells that stimulate cytotoxic T cells.

: Level III: Problem Solving (Bloom's Taxonomy: Application) 206) A compound action potential is recorded using electrodes on a nerve. How does a nerve differ from an axon? Amplitude and duration of a compound action potential vary according to the stimulus intensity applied to the nerve. Given that there is no such variation in the action potential of a single axon, how can you explain this?
: A nerve consists of many axons. A regular action potential is produced by a single axon, whereas a compound action potential is recorded by equipment from a nerve when multiple axons are producing action potentials, and the voltages add together. Increasing stimulus intensity increases the number of axons contributing to the compound action potential. This is because different axons have different threshold voltages, so increasing the voltage stimulates a larger number of axons. Section Title: Electrical Signals in Neurons Learning Outcome: 8.3

She is calling one of her symptoms "heartburn," but reported that it felt as if she had swallowed a small apple whole. Certain that she was having a heart attack, Erica rushed to the doctor. The doctor took her history and symptoms, and reassured her that she only had esophagitis. How did the physician conclude this? Is her blood pH higher or lower than normal?
: Acid reflux irritated the esophageal lining, causing it to swell. Her pH is higher than normal due to loss of H+ from her stomach. Section Title: Anatomy of the Digestive System Learning Outcome: 21.1
: Level III: Problem Solving (Bloom's Taxonomy: Analysis) 136) Chronic inflammation of the pancreas, or pancreatitis, impairs the digestive functions of this organ. What would be the effect on digestion and absorption of carbohydrates, fats, and proteins if acinar cells are impaired? What if duct cells are impaired? Which hormones may be used to treat pancreatitis?
: Acinar cells secrete digestive enzymes for all three classes of molecule, therefore nutrient digestion and consequent absorption would be decreased. Duct cells secrete bicarbonate, which counteracts the acidic nature of the chyme entering from the stomach and allows the pancreatic enzymes to function. The loss of these cells would also decrease digestion and absorption of the three classes of nutrient. Cholecystokinin stimulates pancreatic enzyme secretion and secretin stimulates bicarbonate secretion. Section Title: Secretion Learning Outcome: 21.11
: Level III: Problem Solving (Bloom's Taxonomy: Analysis) 207) Explain the processes that lead to the exocytosis of neurotransmitter from a presynaptic cell. Which components are recycled? Which ion is important in triggering exocytosis?
: Action potential arrives in synaptic terminal, and stimulates opening of voltage-regulated calcium channels. The resulting calcium influx triggers exocytosis of synaptic vesicle contents. The phospholipids of the vesicle membranes are recycled, either from fusion of vesicles then later formation of new vesicles from the same molecules; or from the kiss-and-run model, in which the vesicle phospholipids are not incorporated into the membrane at all, but remain as vesicles that can be refilled with neurotransmitter.

The change in pH as the acid dissociates can be demonstrated with an indicator dye that changes color at a particular pH. In your physiology lab, you perform this experiment in two beakers containing room-temperature water and indicator, labeled as A and B. CO2 is bubbled into solutions A and B from a pressurized tank for 10 seconds. A stopwatch was used to measure how long it took for the solutions to change color. The data below were generated by the students.

: Level III: Problem Solving (Bloom's Taxonomy: Application) 76) Devising new food recipes is more successful when the chefs understand basic food chemistry. For example, to create a new cake recipe, one must understand the role of both acids and bases in leavening (rising, or trapping of tiny gas bubbles as dough is baking, to provide the characteristic texture). The principle is to incorporate baking soda (NaHCO3) into an acidic batter, causing a chemical reaction resulting in gas production. Looking at the chemical formula, what gas do you think is formed? Summarize the chemical reaction that occurs in a cake batter that contains NaHCO3 and vinegar or acetic acid (produces acetate when ionized: CH3COO- + H+). What would happen to your cake if you didn't use enough baking soda? What would happen if you forgot to acidify your batter with vinegar or a similar food acid?
: CO2 gas is formed. NaHCO3 + CH3COO- + H+ → Na+ + CH3COO- + CO2 + H2O. Less gas would be produced, so the cake wouldn't rise normally. The chemical reaction would not occur, so the cake wouldn't rise. Section Title: Acid-Base Balance Learning Outcome: 20.15

: Level III: Problem Solving (Bloom's Taxonomy: Analysis) 135) Cholesterol is absorbed without being digested into smaller pieces. How does this compare to absorption of carbohydrates and proteins? What characteristic of cholesterol suggests it would be transported by simple diffusion? What is the evidence that transport proteins are involved in cholesterol absorption? Does this discovery rule out transport by simple diffusion? Explain.
: Carbohydrates are digested to monosaccharides before they are absorbed. Proteins are absorbed as amino acids, di- or tripeptides, or even oligopeptides. As a lipid, cholesterol can dissolve in the phospholipid bilayer and therefore cross membranes by simple diffusion. The drug ezetimibe inhibits cholesterol absorption, suggesting there must be a membrane transporter. This discovery does not rule out additional transport of cholesterol by simple diffusion, but does suggest there is a significant amount of transport dependent upon a transport molecule.

: Level III: Problem Solving (Bloom's Taxonomy: Application) 68) Dexamethasone is a drug used to suppress the secretion of ACTH from the anterior pituitary gland. Two patients with hypersecretion of cortisol are given dexamethasone. Anika's cortisol secretion level falls to normal after the medication, but Bonnie's cortisol secretion remains elevated. Which patient has primary hypercortisolism, also known as Cushing's syndrome? Explain your reasoning.
: Dexamethasone suppresses the pituitary's activity, the secretion of ACTH, which then allowed Anika's level to decline. Since Bonnie's level did not decline, this shows that the hypersecretion is NOT due to ACTH, thus it must be coming from the adrenal gland. This is the definition of a primary hypersecretion—an elevated amount from the last gland in the reflex pathway. Section Title: Endocrine Pathologies Learning Outcome: 7.8

: ENS is the enteric nervous system, discovered over 100 years ago. The ENS controls reflexive peristalsis in the intestine, independent of the CNS. The ENS is nicknamed the "little brain" because it shares these characteristics with the actual brain: secretion of neurotransmitters and neuromodulators, and the presence of glial cells, a diffusion barrier, and integrating centers.

: Level III: Problem Solving (Bloom's Taxonomy: Comprehension) 199) Compare and contrast the EPSP, IPSP, and action potential as to ions involved, all-or-none law application, specific cellular locations, and specific cell types involved.
: EPSPs and IPSPs are graded potentials in postsynaptic cells resulting from the action of neurotransmitters at synapses, which are usually on dendrites of multipolar neurons, but could also be on the synaptic region of any target cell. EPSPs increase the probability that a postsynaptic action potential will result, because they involve an influx of sodium, which depolarizes the membrane potential, bringing it closer to threshold. IPSPs decrease the probability that a postsynaptic action potential will result, because they involve either an influx of chloride or an efflux of potassium, either of which hyperpolarizes the membrane potential, moving it farther from threshold. Action potentials occur in axons of neurons, or in muscle cell membranes. They may result from PSPs or in the case of sensory neurons, specific stimuli such as sound or odor, which cause a type of graded potential called a receptor potential. Action potentials begin when graded potentials depolarize the membrane potential to threshold. The rising phase of an action potential results from sodium influx, and the falling phase from potassium efflux. Action potentials, but not graded potentials, are an all-or-none phenomenon.

: Level III: Problem Solving (Bloom's Taxonomy: Analysis) 106) Parkinson's disease affects the cerebral basal ganglia, resulting in tremors in limbs, slowness in beginning and completing movements, and other abnormalities of muscle control. The specific population of neurons involved degenerates and thus fails to produce the neurotransmitter dopamine. An obvious treatment option to try is to administer dopamine, yet this is completely ineffective at alleviating the symptoms. Propose a reason why this treatment fails, and a related alternative to address the dopamine deficit. (Hint: Think about how the brain protects itself from chemicals in the blood.)

: Level II: Reviewing Concepts (Bloom's Taxonomy: Application) 98) Explain the role of exposure to antigens in the development of the immune system in the fetus and in the primary and secondary immune responses in children and adults. How does this compare to the role of innate immunity?
: During development, any lymphocytes bearing receptors that bind to molecules in the fetus are eliminated. Thus the only lymphocytes that persist at birth are those that failed to bind to anything, that is, those that have never encountered an antigen. Once the immune system has matured (early in infancy), primary immune responses develop in response to never-before encountered antigens, and secondary immune responses develop with subsequent exposures to the same antigens. Innate immunity is, at all times, independent of prior antigen exposure. Section Title: Acquired Immunity: Antigen-Specific Responses Learning Outcome: 24.5

: During the relative refractory period, a smaller than normal action potential can occur. During this period potassium channels are still open causing repolarization. If a wave of depolarization occurs, Na+ can enter the cells through the newly reopened Na+ channels, but this depolarization is offset by the K+ efflux.

: Insulin promotes glucose transport into most types of cells. Diabetes mellitus results when insulin regulation of blood glucose concentrations is impaired. In type I, the pancreas fails to produce insulin, whereas in type II insulin levels are normal to high, but target cells fail to respond properly. Insulin injections can successfully treat type I but not type II, because the endogenous insulin production in type II is sufficient but the response is abnormal.

: Level III: Problem Solving (Bloom's Taxonomy: Application) 99) If sensitization is the opposite of habituation, and sensitization is adaptive, would habituation be considered maladaptive? Why or why not?
: Habituation is not maladaptive. During habituation, an animal shows a decrease in response to a given stimulus. This stimulus has been processed and determined to be nonthreatening or insignificant. Because the animal has been habituated to ignore this stimulus, it can fade into the background so the animal can focus on other more important stimuli. Habituation is adaptive especially in conjunction with sensitization because the animal can differentiate and ignore certain irrelevant stimuli (through habituation) and focus more intently on potentially dangerous stimuli (sensitization).

Inflammation is characterized by redness, swelling, increased temperature, etc., but these symptoms are caused by one's own immune system, either fighting off the pathogen or repairing tissue damage, or both. It is also possible to have inflammation, such as with a sprained ankle, without infection. Section Title: Innate Immunity: Nonspecific Responses Learning Outcome: 24.11
: Level II: Reviewing Concepts (Bloom's Taxonomy: Application) 124) Explain how the analogy of a ball and a hill is useful for describing the forms of energy to beginning physiology students. Use the synthesis of glucose by plants and the break down of glucose by humans as specific examples of the energy hill.
: Energy is required for a person to move a ball from a lower height to a higher one, and that the ball will automatically roll down the hill if allowed to, without further input of energy. The substrates CO2 and H2O require energy to be combined into C6H12O6; the energy of the sun provides this energy to "roll" the substrates up the energy hill as they combine. The glucose then contains the potential energy provided by the sun. When enzymes are present, the molecule easily breaks down to CO2 and H2O releasing energy that is used by the cell to perform work.

: False. A target tissue's response is dependent upon the exact receptor involved, as well as a variety of other factors. For example, insulin causes skeletal muscle to increase its rate of transport of glucose into the cell, but in the liver insulin affects the activity of enzymes not directly related to glucose transport.

: Level II: Reviewing Concepts (Bloom's Taxonomy: Comprehension) 116) Proteins must first be enzymatically degraded to single amino acids before entering the capillaries of the hepatic portal system. Is this true or false? What is the significance of this? Is absorption of carbohydrates and lipids restricted to monomers? Explain.
: False. Absorption of small peptides allows peptides to provoke food allergies. The transporters for peptides are also responsible for absorption of some drugs. Carbohydrates are digested to monosaccharides because there are no transporters for larger carbohydrates. Lipids are absorbed as cholesterol, fatty acids, and monoglycerides, primarily by simple diffusion because they are lipophilic. Section Title: Digestion and Absorption Learning Outcome: 21.10
: Level II: Reviewing Concepts (Bloom's Taxonomy: Application) 122) True or False? Lipids contain substantially more oxygen than carbohydrate molecules. Based on your answer, what does that suggest about lipid solubility in water?
: False. Lipids contain much less oxygen than carbohydrates. Oxygen often participates in hydrogen bonding. With less oxygen, lipids are not able to hydrogen bond with water molecules and therefore are relatively insoluble in aqueous environments.

: Level II: Reviewing Concepts (Bloom's Taxonomy: Knowledge) 192) "A refractory period occurs following all types of potentials." Is this statement TRUE or FALSE? What structures are actually refractory? Why or why not?
: False. The refractory period occurs after action potentials and is a distinguishing characteristic, and results from properties of the voltage-gated sodium channels. Graded potentials do not involve channels that have refractory periods. Two stimuli that reach a dendrite at nearly the same time will increase the graded potential produced, whereas if two suprathreshold depolarizations reach the trigger zone at nearly the same time, the first will cause an action potential and the second will be ignored, because of the refractory period.

: Level II: Reviewing Concepts (Bloom's Taxonomy: Comprehension) 183) Compare and contrast fast and slow synaptic potentials, including detailed mechanisms used and what kinds of cells they occur in.
: Fast synaptic potentials begin quickly and last only a few milliseconds; this category includes EPSPs and IPSPs. Slow synaptic potentials take longer to begin and last longer commonly involve G-protein coupled receptors; this type of response is important in growth, development, and long-term memory. Section Title: Integration of Neuronal Information Transfer Learning Outcome: 8.7
: Level III: Problem Solving (Bloom's Taxonomy: Analysis) 116) Explain the role of experience in the immune system. Given the importance of experience, is a person's immune response determined by the genes or the environment? Explain.
: Fetal development of the immune system involves elimination of lymphocytes that can bind to self cells. Secondary exposures to a given antigen result in a faster and more vigorous immune response due the persistence of memory cells that were created following the first exposure. But the immune response is ultimately genetic because lymphocytes recognize antigens as a result of having specific complementary membrane receptors, and these receptors are proteins whose amino acid sequence and thus 3-D shape are determined by the DNA.

What type of disturbance is Gossip suffering from and what might cause this? If his PCO2 were elevated, would your answer change? Explain.
: Gossip is likely suffering from metabolic acidosis, since his PCO2 is normal. If his PCO2 was elevated, then he would likely be suffering from respiratory acidosis. Metabolic acidosis may be caused by ingestion of methanol, aspirin, and ethylene glycol. Respiratory acidosis can be caused by drugs or alcohol depression, increased resistance in asthma, impaired gas exchange in fibrosis or severe pneumonia, and muscle weakness in muscular dystrophy and other muscle diseases. The most common cause is chronic obstructive pulmonary disease. Section Title: Acid-Base Balance Learning Outcome: 20.18

: Graphs should resemble Figure 24.8 in the chapter. In a primary response, antibody is not detectable until several days after exposure to antigen, and peak antibody concentration is lower than it is in a secondary response. The secondary response shows a more immediate and steep increase in concentration. This more rapid and vigorous response indicates that the memory cells retained following the first exposure proliferate more readily.

Each of these diseases is inherited. Explain how there might be a relationship among these observations.
: Inheritance is determined by the message coded into DNA; a mutation relays a faulty message, which disrupts protein synthesis, resulting in either a faulty protein or complete absence of the protein. Enzymes are proteins. When the instructions for the synthesis of their structure are changed, they may not be able to perform their function, producing a disease condition. If the disease is not fatal prior to puberty and does not render its victim unable to reproduce, the faulty DNA will be copied during gametogenesis and will appear in a predictable percentage of offspring.

: Level II: Reviewing Concepts (Bloom's Taxonomy: Analysis) 100) Describe the roles of interleukins, kinins, and complement in immunity. How does interleukin-1 mediate the immune response?
: Interleukins mediate the inflammatory response, induce fever, stimulate cytokine and endocrine secretion, and promote other aspects of immune response. Kinins are inactive plasma proteins that are part of a cascade producing the end-product bradykinin. Bradykinin promotes inflammation and causes pain. Complement proteins are part of a cascade producing a membrane attack complex that can lyse pathogens. Complement proteins stimulate other aspects of the immune response as well.

Her father says the stress from finals probably caught up with her and she just needs to rest. What do you think? Is Shannon's father right? Could stress have caused her to get sick? If not, why not? If so, what mechanisms were at play?
: It is possible that stress can be part of the problem. Increased stress causes a raise in the levels of cortisol in the blood and cortisol can actually decrease antibody production, lymphocyte proliferation, and reduce the activity of natural killer cells. If she had been exposed to some pathogen like the flu virus, it is possible that the effects of the sympathetic nervous system could have suppressed symptoms while elevated, but also reduced the effectiveness of the immune system, so when the sympathetic rush was over after finals, she started to noticed the signs of her infection.

: Level IV: Quantitative Problems (Bloom's Taxonomy: Comprehension) 223) Draw a graph showing what would happen to resting membrane potential over time, if the sodium/potassium pump were not functioning. How would this affect a neuron's ability to produce action potentials? What does this imply about the quantity of ions that normally cross the membrane during the course of an action potential?
: It would be appropriate for the student to draw action potentials on the graph beginning at the point where the resting potential drifts up to threshold, and decreasing in frequency as the resting potential approaches. Very gradually, a cell's resting membrane potential would increase until it reached and stabilized there. At that point the ions would be in equilibrium, and no further net flow of charge would occur. There would be no effect on ability to generate action potentials initially, but with the disappearance of the differential distribution of sodium and potassium upon which the action potential depends, action potentials would gradually come to a stop. This points out the fact that during any single action potential, so few ions cross the membrane that there is no significant change in ion concentrations. Thousands of action potentials would be required before the absence of the sodium-potassium pumps would be noticeable. Section Title: Electrical Signals in Neurons Learning Outcome: 8.4

Patrick, a regular customer in your section, has ordered sweet iced tea and has an appointment in 10 minutes, so he must drink quickly then leave. The kitchen staff makes only unsweetened tea, but there are sugar packets on the tables. What should you do for Patrick to provide the best sweet tea, and what general principle of diffusion does this illustrate? (Hint: Will sugar dissolve quickly in an iced drink?)
: Make sugar syrup for Patrick by heating a small amount of water with a generous amount of sugar. The sugar diffuses through the water as it dissolves, and this will occur much quicker in warm water (diffusion rate increases with increasing temperature). Then add the syrup to his iced tea and serve. Section Title: Osmosis and Tonicity Learning Outcome: 5.3
: Level II: Reviewing Concepts (Bloom's Taxonomy: Application) 120) Explain how enzymes can be useful in the diagnosis of disease, giving specific examples. Is the change in enzyme concentration a direct or indirect result of the disease?
: Many enzymes are normally present in the blood in a particular range of concentrations. Alterations in these concentrations can be associated with abnormal conditions. For example, elevation in the digestive enzyme amylase, produced by the pancreas, may indicate pancreatic disease. Elevation of enzymes that normally operate inside cells can indicate tissue damage, such as the elevation of creatine kinase following myocardial infarction. Low amounts of hexosamidase A can indicate Tay-Sachs disease. In the examples given, the amylase and hexosamidase enzyme changes are direct results of the disease, whereas enzymes elevated because of tissue damage are the result of cellular damage and not a direct change in the enzyme itself.

: One benefit of a portal system is that it ensures that the controlling hormones will be delivered directly to the target cells. Secondly, since the hormones go directly to their target cells without first passing through the general circulation they are not diluted. The hypothalamus can control the cells of the pituitary with much smaller amounts of releasing and inhibiting hormones than would be necessary if the hormones had to first go through the circulatory pathway before reaching the pituitary. This is the only endocrine portal system. Section Title: Control of Hormone Release Learning Outcome: 7.3

: Level III: Problem Solving (Bloom's Taxonomy: Analysis) 133) If someone has a muscle cramp or spasm, a commonly discussed treatment is to consume a banana (or another food high in potassium). Why would this be a possible treatment for muscle cramps or spasms?
: Potassium is a cation that leaves the cell during an action potential or depolarization of a muscle or nerve cell, and the muscle or nerve cell needs to move potassium back into the cell to allow the cell to repolarize and relax. If there is a deficiency in potassium, muscle and nerve cells may take longer to repolarize and therefore relax, so increasing your dietary intake of potassium may help cells repolarize quicker.

Are these processes mutually exclusive, or can they occur at the same time in a typical multipolar neuron? What key property of neurons do these forms of summation demonstrate?
: See Figs. 8.24 and 8.25 in the chapter. Temporal summation is the addition of graded potentials that overlap in time; that is, a second potential arrives before the first one from that source has finished. Spatial summation occurs when there is simultaneous arrival of graded potentials originating from more than one synaptic input. Summation occurs at the trigger zone. Typically a multipolar neuron has many active synapses at a given time, with multiple potentials being produced at each. Summation demonstrates postsynaptic integration.

: Level III: Problem Solving (Bloom's Taxonomy: Analysis) 126) Cody has always carefully controlled her caloric intake, and is lean. During her unplanned pregnancy, she continued to eat the same, hoping that taking prenatal vitamins and minerals would ensure that her fetus would grow normally. Her only complication during pregnancy was persistent constipation and consequent hemorrhoids. She gained only the minimum weight suggested by her doctor, and delivered a healthy, full-term infant; her pre-pregnancy weight was rapidly reestablished. Propose an explanation for how she managed to gain enough weight, did not violate the law of conservation of mass, and for her only complication. What does this suggest about "eating for two" that some pregnant women do?
: She must have inefficiently absorbed calories prior to her pregnancy, losing many potential calories in her feces. When she became pregnant, one of her physiological changes included an increase in nutrient (and thus calorie) absorption. This would also contribute to her constipation, as her feces retained less water than normal and thus were more difficult to eliminate. It is not possible for her to have gained more weight than she ate; no one can violate the law of conservation of mass. Most obstetricians recommend only a slight increase in calories during pregnancy for this reason, and women who indulge in overeating too often are likely to gain unnecessary body fat and may produce a fetus that is larger than it should be.

: Sleep is composed of four different stages and during sleep one repeatedly cycles from one stage to another. Stage 4 is slow-wave in deep sleep that can be identified by low-frequency high-amplitude EEG delta waves. This stage occurs more during the beginning of sleep. Stage 3 is characterized by a lower amplitude but higher frequency EEG wave pattern. Stage 2 is characterized by an even lower amplitude and even higher frequency EEG wave pattern. This cycle lasts for longer durations as a typical 8 hour sleep progresses. Stage 1 is REM: Rapid eye movement is characterized by dreaming and low amplitude high frequency EEG waves. Most motor neurons (e.g., except eye and breathing motor neurons) are inhibited while dreaming is occurring. REM occurs for longer time periods during later parts of the sleep cycle.
