Question 1
pts
The neuron pictured, below, is best described as:
,2026
Correct!
Bipolar
It has two extensions from the central cell body.
Multipolar
Unipolar
Pseudounipolar
,2026
Question 2
Not yet graded / 10 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.
● 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 +40 mV.

Where is the integration center of a reflex located?
CNS (central nervous system)
Question 4
pts
What is false about the flexor withdrawal reflex?
A. It does not involve interneurons.
B. It involves excitatory interneurons.
C. It involves inhibitory interneurons.
D. The effect of the reflex is to create a co-contraction of two muscles
