Which therapeutic intervention would be most appropriate for someone suffering from treatment-resistant bulimia?
Cognitive behavioral therapy
Which pancreatic hormone promotes the conversion of glucose to glycogen?
Insulin
What is the effect of injecting of anandamide into the hypothalamus?
It stimulates eating.
One of the primary causes of eating disorders is believed to be
a cultural that emphasizes thinness as being attractive.
Angiotensin II acts on the _______ to provoke the release of _______.
adrenals; aldosterone
Neuropeptide Y (NPY) neurons and pro-opiomelanocortin (POMC) neurons have opposing effects on _______ and _______.
appetite; metabolism
About 10-20% of the energy we ingest is used for _______ processes.
behavioral
The stimuli associated with food, such as its smell, provoke the release of insulin during the _______ phase.
cephalic
Two physiological responses to hypovolemia are _______ of blood vessels and the secretion of _______ by the posterior pituitary.
constriction; vasopressin`
The body fluid compartments change with _______ upon severe water loss.
decreased blood pressure and decreased plasma volume
Injecting PYY3-36 into rats causes them to
eat less
In mammals, the saltiness of the _______ environment _______.
extracellular; is similar across species
Endotherms may show a significant departure from their average body temperatures as a consequence of
fever
The body stores glucose for later use after first converting it to a more complex form called
glycogen
One of the reasons we know that insulin is not the only cue for satiety is that
high doses of insulin initiate eating.
Research using fMRI shows that drinking glucose after fasting induces activity in the
hypothalamus.
One of the selective advantages of endothermy appears to be
increased capacity to sustain a high level of muscular activity.
Physiological saline is also sometimes described as
isotonic
Under conditions of prolonged food deprivation, fat can be converted into glucose and a secondary form of fuel, called
ketones
Which structure produces angiotensin II?
kidneys
Behavioral regulation of body temperature, like moving closer to the fire, is especially affected by lesions of the
lateral hypothalamus.
The population of beneficial bacteria, fungi, and viruses that inhabit the large intestine of human beings is referred to as a
microbiome
The response to increase in the salt concentration of the extracellular solution is called _______ thirst.
osmotic
The two main kinds of thirst are _______ thirst and _______ thirst.
osmotic; hypovolemic
People with a BMI of 25-30 are in the body weight level of
overweight
Thermoregulation is considered a negative feedback system because
restoring the desired temperature turns off the response.
In rats, lesions of the ventromedial hypothalamus (VMH) lead to all of the following except
self-maintenance of normal weight.
Research on the effects of leptin indicates that activation of POMC neurons in the hypothalamus
suppresses hunger.
When a cell comes into contact with pure water it
swells
When an animal loses a lot of blood, there is a tendency of baroreceptors to signal
thirst
One of the reasons we know that glucose cannot be the only cue for satiety is that
untreated diabetics are hungry.`
Which example demonstrates ectothermic behavior?
A turtle basking on a sunny log
Which items are incorrectly paired?
Bulimia nervosa; significant weight loss
Anticipation of glucose in the blood facilitates which phase of insulin release?
Cephalic
Which intervention or research findings has not been an effective weight loss strategy?
Drugs that block the visual appeal of food
Which method is not a current strategy for treating obesity?
Drugs that increase digestive acid levels in the stomach
Which pair of hormones have opposing effects on NPY neurons?
Ghrelin and PYY3-36
Which pancreatic hormone promotes the conversion of glycogen to glucose?
Glucagon
_______ refers to the active process of maintaining a relatively stable internal environment.
Homeostasis
Which circumventricular organ contains osmosensory neurons?
Organum vasculosum of the lamina terminalis (OVLT)
Which statement about anorexia nervosa is true?
People with anorexia think about food a great deal.
What is the significance of a set zone, as opposed to a precise set point, in terms of thermoregulation?
The wide variety of conditions that animals face makes a tolerance, or set zone, instead of a precise set point, more adaptable.
Which molecule is known as antidiuretic hormone?
Vasopressin
