ASU BIO 181 Exam 3 Questions and
Correct Answers the Latest Update and
Recommended Version
Excitatory synapses make the post-synaptic cell less likely to fire.
✓ False
The neural tissues are:
✓ Spinal cord, sensory neurons, and brain
How do the glial cells (i.e., myelin sheath) speed up the firing of neurons?
✓ The cell wraps extensions of a fatty insulating substance (myelin) around the axons of
neurons.
The action potential is:
✓ A result of the movement of ions.
Receptors are made from membrane-bound polyribosomes.
✓ True
List the 4 types of glial cells and list a phrase to describe their function.
✓ Microglia: cleans up cellular debris- Astrocytes: support and repair neurons- Schwann
Cells: myelinates axons of the neurons in the PNS- Satellite: form the brain-blood barrier
within the CNS
Acetylcholine exocytosed from the presynaptic cell travels to the postsynaptic cell to start the
action potential in the postsynaptic cell.

✓ True
When the presynaptic cell contacts a muscle cell, the synapse area is called a motor end
plate.
✓ True
Potassium ions are at high concentrations inside of cells including in neurons.
✓ True
The membrane potential (resting potential) is largely set by the Na-K- ATPase pump.
✓ True
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.
✓
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
Voltage-gated ion channels open when a protein binds to the receptor.
✓ False
