MEYERS UNIT 3 Practice test questions (robb)
The process by which neurotransmitters are reabsorbed into the neuron after it fires is called
reuptake
An image projected to the left visual field of a split-brained person will be processed in the
right visual cortex
describes the firing of neurons
An all-or-none response
For most people, speech functions are primarily localized in the
leftcerebral hemisphere
Dopamine, norepinephrine, and acetylcholine are all
neurotransmitters that excite or inhibit a neural signal across a synapse
The part of the neuron that is responsible for receiving signals from other neurons is called
a dendrite
The brain scans of people with amnesia are most likely to show damage to the
hippocampus
The area of the brain stem that is important in controlling breathing is the
medulla
true of the reticular activating system?
It regulates levels of arousal.
caffeine and nicotine are in the same class as this drug
cocaine
Would result from an injury to the medulla?
A life-threatening disruption of heartbeat and breathing
Damage to the cerebellum would most likely result in
A loss of motor coordination
If an individual has lost the ability to feel pain in the left arm, there is most likely damage to what area of the brain?
Right parietal lobe
The drugs that block the reabsorption of neurotransmitters in the synapse during neural transmission are
SSRIs
A person with damage to Broca's area would most likely demonstrate
difficultly with speech production
The autonomic nervous system is most directly involved in
digesting food
alcohol interferes with the brain's ability to form new memories in the
hippocampus
This drug is a antagonist
A tricyclic antidepressant, because they block serotonin and norepinephrine transporters.
The depletion of this neurotransmitter is most closely associated with the symptoms of Alzheimer's disease?
Acetylcholine
Damage to this brain structure may cause the inability to detect the emotional significance of facial expressions, especially those demonstrating fear?
Amygdala
Brain damage to this part leaves a person capable of understanding speech but with an impaired ability to produce speech
Broca's area
What allows the examination of living brain tissue visually without performing surgery?
Computerized axial tomography
alcohol is most accurately classified as what type of drug?
Depressant
Cocaine blocks the reuptake of which neurotransmitter?
Dopamine
Which of the following neurotransmitters has been linked to Parkinson's disease and schizophrenia?
Dopamine
Most glands in the human body are a part of which system?
Endocrine
In extreme cases, surgically severing the corpus callosum is a treatment for which of the following conditions?
Epilepsy
a brain-imaging technique that produces the most detailed picture of brain structure
Magnetic resonance imaging (MRI)
Which of the following provides information regarding brain function by monitoring the brain at work through metabolism of glucose?
Positron emission tomography (PET)
A technique that researchers inject a harmless, radioactive substance into the living human brain to examine activity?
Positron-emission tomography (PET)
Significant damage to this part will cause a person to fall into a deep coma from which the person will be unable to awaken?
Reticular formation
Neurotransmitters are typically stored in which of the following parts of a neuron?
The terminal buttons
A person will most likely develop aphasia as a result of damage to the
Wernicke's Area
Electrically stimulating a rat's amygdala would most likely produce which of the following?
aggression
A drug that has the effect of intensifying or mimicking a particular neurotransmitter can be characterized as
an agonist, because it intensifies the effects of a particular neurotransmitter
When a person is suffering from severe pain, the type of drug that will best help alleviate that pain is
an opiate
Curare blocks action at acetylcholine synapses and causes paralysis. This drug is an example of an
antagonist
A polygraph machine is often called a "lie detector," although it does not detect lies. Instead, it responds to changes in
autonomic arousal
An individual with damage to Wernicke's area is most likely to have difficulty
comprehending a spoken request for information
technique involving electrodes attached to scalp
electroencephalography (EEG)
Painkilling substances produced by the brain are known as
endorphins
The part of the endocrine system that is responsible for overseeing and regulating the release of hormones across the entire body is the
hypothalamus
Give increase in energy and feelings of well being during exercise
increases her level of endorphins
pupils dilated, sweating, and his heart accelerated. These changes are most closely related to the function of the
sympathetic nervous system
During neuronal firing, the part of the neuron that acts as an insulator and conductor to speed the electrical impulse as it travels down the axon is
the myelin sheath
The time shortly after a neuron fires is referred to as
the refractory period
Damage to a small part of the occipital lobe would most likely result in a
visual deficit
