The ventral root of a nerve contains what type of neurons? - ANSWER motor (efferent)
This part of the autonomic system accelerates the heart beat and increases breathing rate. -
ANSWER sympathetic nervous system
This is a bundle of axons found in the peripheral nervous system. - ANSWER nerve
This part of a neuron conducts nerve impulses towards the cell body. - ANSWER dender-
ites
A neuron going to the bicep of the forearm is part of the: - ANSWER A. Central nervous
system
B. Peripheral nervous system
C. Autonomic system
D. Somatic system
E. A&C
Correct! F. B&D
The neuron pictured, below, is best described as: - ANSWER A) Bipolar
B) Correct! Multipolar
C) Unipolar
D) Pseudounipolar
True or false: Neurons do not physically touch one another. - ANSWER True
1
, Neurons do not physically touch. They are separated by synapses.
Describe the synthesis and storage of neurotransmitters. - ANSWER The neuron cell body
manufactures neurotransmitters, which are stored in secretory vesicles at the end of axon
terminals.
An afferent neuron carries information: - ANSWER A) From the central to the peripheral
nervous system
B) Correct Answer From the peripheral to the central nervous system
C) Within the central nervous system
D) Within the peripheral nervous system
A presynaptic neuron would be found: - ANSWER A) Correct Answer Before the synapse
B) After the synapse
C) Inside the synapse
D) Only in the peripheral nervous system
What is the location and function of Satellite cells? - ANSWER Location: Peripheral nerv-
ous 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 re-
grow axons in their spinal cord? Why or why not? - ANSWER No; Only peripheral system
axons are capable of regeneration. The spinal cord is in the central nervous system.
Name and describe what is occurring in the neuron cell membrane in section 4 of the dia-
gram. Include the charge of the membrane during this phase. - ANSWER Afterpolariza-
tion (Hyperpolarization) Potassium gates are slow to close and there is an undershoot of the
potential.
The charge drops below -70mV and then returns to -70mV once at resting state again.
