Bio 360: Animal Physiology Exam 1 (multiple choice
questions from quiz bank for exam 1 (metabolism, transport,
and the nervous system) Questions With Complete Solutions
. What are the reasons for sensing a pitch? (Select all that apply.)
Correct Answers Different pitches activate different hair cells..
The basilar membrane differs in stiffness across its length, and
so different parts vibrate to different frequencies.
A drug that block monoamine oxidase will tend to increase the
strength of a synapse that uses dopamine as the neurotransmitter
or modulator. Correct Answers true
A drug that blocked the Na+/K+ ATPase would have what
effect on ion concentrations and the membrane potential?
Correct Answers Ion concentrations would slowly equalize, and
over time, the membrane potential would go toward zero.
A finer sense of discrimination usually is made possible by
having larger receptor cells Correct Answers False
A strong stimulus is sensed by the brain as larger magnitude
action potentials. Correct Answers False
A strong stimulus is sensed by the brain as larger magnitude
action potentials. Correct Answers False
Acetylcholine is an amino acid. Correct Answers false
,Activation of NMDA receptors by glutamate can lead to
increases in calcium levels in the postsynaptic cell. Correct
Answers true
After a stroke, Mary has trouble seeing out of her left eye. This
most likely indicates damage to the _____________. Correct
Answers right occipital lobe
Alzheimer's disease often affects cholinergic neurons. Correct
Answers true
Anti-anxiety drugs often act on glycine receptors. Correct
Answers false
Assuming a synapse is excitatory, which of the following would
tend to strengthen a synapse? Correct Answers A drug that
inhibits an enzyme in the synaptic cleft that degrades the
neurotransmitter
Blocking the voltage-gated sodium channels will have what
effect on the action potential? Correct Answers The membrane
will not depolarize (no action potential).

Choose the true statements about sensory neurons (choose all
that are correct): Correct Answers sensations on the left side of
the body map to the right side of the brain
stronger sensations usually are associated with higher
frequencies of action potentials in the sensory neuron
Choose the true statements about the peripheral nervous system:
Correct Answers Nicotine binds to receptors at the
preganglionic synapse for both the sympathetic and
parasympathetic nervous system
