Combination of all tests:
Module 1- Nervous System Intro
1. This is a collection of cell bodies found in the peripheral
nervous system. Ganglia
1. This is a bundle of axons found in the peripheral nervous
system. Nerve
2. This part of the autonomic system increases digestion.
Parasympathetic
3. The ventral root of a nerve contains what type of
neurons? Motor neurons
4. This part of a neuron conducts nerve impulses towards
the cell body.
Dendrites
5. A neuron going to the bicep of the forearm is part of the:
Peripheral nervous system and somatic system
, lOMoAR cPSD| 67691079
6. The neuron pictured, below, is best describes as:
Multipolar neuron
7. True or false: Neurons come into direct physical contact
with one another.
False: neurons do not physically touch. They are separated by
synapses.
7. True or false: Neurons do not physically touch one
another. True.
8. Describe the function and release of neurotransmitters.
, lOMoAR cPSD| 67691079
When neurotransmitters are released by the axon
terminal vesicles, they carry the transmission of the nerve
impulse from one neuron to another.
8. Describe the synthesis and storage of neurotransmitters
They are synthesized by neuron cell bodies and stored in
secretory vesicles at the end of axon terminals.
9. An efferent neuron carries information:
From the central to the peripheral nervous system
10. A postsynaptic neuron would be found:
After the synapse
10. A presynaptic neuron would be found
Before the synapse
11. What is the location and function of Satellite cells?
Location: Peripheral nervous system (PNS) Function:
Regulation of environment of neuron cell bodies
, lOMoAR cPSD| 67691079
12. A patient's spinal cord was served in a car accident.
Would the patient be expected to regrow axons in their
spinal cord? Why or why not?
No because only peripheral systems axons can regenerate
12. A patient’s left thumb was severed in a car accident and
then reattached during surgery. Would the patient be
expected to regrow axons in their thumb? Why or why
not?
Yes, Schwann cells will grow ahead of the axon, allowing for
peripheral nerves to regenerate the length of the axon via
axonal regeneration.
13. Name and describe what is occurring in the neuron cell
membrane in section 4 (2) of the diagram. Include the
charge of the membrane during this phase.
• Phase 1 : Resting Potential: During the resting phase,
both sodium and potassium gates are closed. -70Mv
• Phase 2 : Depolarization: The sodium gates open, and
sodium rushes into the axon during the depolarization
phase of the action potential. Voltage travels to zero and
then on up to +40 mV.
