BIOD 152 Module 1 Exam
Question 1
2..5 pts
This is a collection of cell bodies found in the peripheral nervous system.
Ganglia
Question 2
2..5 pts
This part of the autonomic system accelerates the heart beat and increases breathing rate.
Sympathetic
Question 3
2..5 pts
The dorsal root of a nerve contains what type of neurons?
Sensory (Afferent)
Question 4
2..5 pts
This part of a neuron conducts nerve impulses towards the cell body.
Dendrites
Question 5
pts
A neuron going to the bicep of the forearm is part of the:
A. Central nervous system
B. Peripheral nervous system
C. Autonomic system
D. Somatic system
E. A&C
Correct!
,F. B&D
Question 6
pts
The neuron pictured, below, is best described as:
Bipolar
Correct!
Multipolar
Unipolar
Pseudounipolar
Question 7
pts
True or false: Neurons do not physically touch one another.
,Correct!
True
Neurons do not physically touch. They are separated by synapses.
False
Question 8
pts
Describe the function and release of neurotransmitters.
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.
Question 9
pts
An afferent neuron carries information:
From the central to the peripheral nervous system
Correct!
From the peripheral to the central nervous system
Within the central nervous system
Within the peripheral nervous system
Question 10
pts
A postsynaptic neuron would be found:
Before the synapse
Correct!
After the synapse
, Inside the synapse
Only in the central nervous system
Question 11
pts
What is the location and function of Satellite cells?
Location: Peripheral nervous system (PNS)
Function: Regulation of environment of neuron cell bodies
Question 12
pts
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?
Yes; Peripheral nerves can regenerate the length of the axon through axonal
regeneration because of the growth of Schwann cells ahead of the axon.
Question 13
pts
Name and describe what is occurring in the neuron cell membrane in section 2 of the diagram.
Include the charge of the membrane during this phase.
