Sensory (afferent)
This part of a neuron conducts nerve impulses away from the cell body.
Axon
A neuron going to the bicep of the forearm is part of the:
,A. central nervous system
B. peripheral nervous system
C. Autonomic system

The neuron pictured, below, is best described as:
A. Bipolar
B. Multipolar
C. Unipolar
D. Pseudounipolar
B. Multipolar
True or false: Neurons do not physically touch one another.
True
Describe the synthesis and storage of neurotransmitters.
The neuron cell body manufactures neurotransmitters, which are stored in secretory
vesicles at the end of axon terminals
,An efferent neuron carries information:
A. From the central to the peripheral nervous system
B. From the peripheral to the central nervous system
C. Within the central nervous system
D. Within the peripheral nervous system
A. From the central to the peripheral nervous system
A postsynaptic neuron would be found:
A. before the synapse
B. after the synapse
C. inside the synapse
D. Only in the central nervous system
B. after the synapse
What is the location and function of Satellite cells?
Location: peripheral nervous system (PNS)
Function: Regulation of environment of neuron cell bodies
A patient's spinal cord was severed in a car accident. Would the patient be expected to
regrow axons in their spinal cord? Why or why not?
No, only the peripheral system axons are capable of regeneration. The spinal cord is the
central nervous system
, We have an expert-written solution to this problem!
Name and describe what is occurring in the neuron cell membrane in section 4 of the
diagram. Include the charge of the membrane during this phase.
This is phase 4: afterpolarization (hyperpolarization), the potassium gates are slow to clse
and that results in an undershoot of the potential, the voltage will drop below -70mV and
the return to the restign state beings.
At rest, a neuron plasma membrane is:
A. -70 mV
B. +40 mV
C. Hyperpolarized
D. Depolarized
A. -70 mV
Which of the following is false concerning the sodium-potassium pump?
A. it maintains the resting phase of an axon
B. For every three sodium ions pumped out, two potassium ions are pumped in
C. it must remain in constant operation to maintain the resting state
D. The overall effect is a negative charge on the outside of the membrane
D. The overall effect is a negative charge on the outside of the membrane
