Portage Learning A&P II: Final Exam Questions with
correct Answers
This is a collection of cell bodies found in the peripheral nervous system
- ANS--Ganglia
This part of the autonomic system accelerates the heart beat and
increases breathing rate. - ANS--Sympathetic
The dorsal root of a nerve contains what type of neurons? - ANS--
Sensory (Afferent)
True or False: Neurons do not physically touch one another. - ANS--
True-Neurons do not touch each other, they are separated by synapses
Describe the function and release of neurotransmitters. - ANS--
Neurotransmitters are chemicals stored inside secretory vesicles (axon
terminal vesicles) at the end of the axon terminals. When
neurotransmitters are released by the axon terminal vesicles, they carry
the transmission of the nerve impulse from one neuron to another.
An afferent neuron carries information: - ANS--From the peripheral to
the central nervous system
A postsynaptic neuron would be found: - ANS--After the synapse

correct Answers
This part of a neuron conducts nerve impulses towards the cell body. -
ANS--Dendrites
A neuron going to the bicep of the forearm is part of the: - ANS--
Peripheral Nervous System and Somatic System
What is the location and function of Satellite cells? - ANS--Location:
Peripheral nervous system (PNS)
Function: Regulation of environment of neuron cell bodies
A patient's left thumb was severed in a cooking accident and then
reattached during surgery. Would the patient be expected to regrow
axons in their thumb? Why or why not? - ANS--Yes; Peripheral nerves
can regenerate the length of the axon through axonal regeneration
because of the growth of Schwann cells ahead of the axon.
At rest, a neuron plasma membrane is - ANS---70mv
Which of the following is false concerning the sodium-potassium
pump? - ANS--The overall effect is a negative charge on the outside of
the membrane. (False, the effect of the pump is a negative charge
inside the membrane, positive on the outside)
