BIO 181 ASU CAPCO EXAM 3
CERTIFICATION TEST 2026
COMPREHENSIVE QUESTIONS AND
SOLUTION GUIDE
◉ The resting potential of neurons is: -60 mv (The answer is not
on this list.)
◉ T/F The autonomic nervous system contains the sympathetic and
the parasympathetic nervous system. True
◉ In the motor end plate, the event that is the immediate trigger for
exocytosis is: Calcium Ions
◉ Draw an action potential in the axon of a neuron and indicate
which ions flow into the neuron and out of the neuron as the action
potential passes at the point where the electrodes are in the cell. Be
sure to assign on the Y-axis the mV of each of these areas. This
should be as described in my lectures.
◉ The action potential is: A result of the movement of ions.
, ◉ T/F The cell body refers to the part of the neurons that begin at
the dendrites and extend to the axon terminal. False
◉ T/F When the presynaptic cell contacts a muscle cell, the synapse
area is called a motor end plate. True
◉ The post-synaptic cell can be: In glands, muscle cells, neurons
◉ T/F Excitatory synapses cause depolarization of the post-synaptic
cell. True
◉ T/F Only pre-synaptic neurons are coated with myelin. False
◉ T/F Fast neurons as described in lecture are fast because they are
surrounded by a type of glial cell that results in a myelin coating.
False
◉ T/F The axon from a pre-synaptic cell contacts the axon of
another neuron. False
◉ List the 4 types of glial cells and list a phrase to describe their
function. - Microglia: Are part of the cellular immune system to
