Quiz____?
the dorsal root of a nerve contains what type of neurons? -
Answer✓✓
sensory/ afferent
Quiz____?
this part of a neuron conducts nerve impulses towards the cell body -
Answer✓✓

Page 1 of 16
,Answer✓✓
central nervous system and autonomic nervous system
Quiz____?
the neuron pictured below is best described as -
Answer✓✓
bipolar
Quiz____?
T/F: neurons do not physically touch one another -
Answer✓✓
true
Quiz____?
describe the function and release of neurotransmitters -
Answer✓✓
-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
Quiz____?

Quiz____?
a patient's 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 -
Answer✓✓
yes; PNS nerves can regenerate the length of the axon through axonal
regeneration because of the growth of Schwann cells ahead of the axon
Quiz____?
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 -
Answer✓✓
-depolarization: the sodium gates open and sodium rushes into the axon
during the depolarization phase of the action potential
-voltage travels past zero and then on up to +40mV
