,BIO 152 / BIOD 152 AP 2, FINAL 2021
Correct!
Bipolar
It has two extensions from the central cell body.
Multipolar
Unipolar
Pseudounipolar
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.
, BIO 152 / BIOD 152 AP 2, FINAL 2021
● 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.
Question 3
