Accepted Answer

Myelin sheath

Question 4

Which of the following best explains how Schwann cells form the myelin sheath around axons?

They wrap their plasma membrane repeatedly around the axon

Question 5

Which anatomical feature determines whether a neuron is classified as unipolar, bipolar, or multipolar?

Accepted Answer

The number of processes extending from the cell body

Question 6

Which of the following correctly matches the neuroglial cell with its function in the CNS?

Question 8

Which connective tissue covering surrounds individual nerve fibers (axons) within a nerve?

Accepted Answer

Endoneurium

Question 9

Which of the following best describes the role of the axon hillock in a neuron?

Accepted Answer

It is the region where action potentials are initiated

Question 10

If the frequency of stimulatory impulses to a muscle is gradually increased while keeping the voltage constant, what is the expected effect?

Accepted Answer

The muscle will show increased recruitment and stronger contractions

Which of the following is a major function of astrocytes in the CNS?

Accepted Answer

Controlling the chemical environment around neurons

Question 12

Which of the following best describes the process of recruitment in muscle physiology?

Question 19

Which of the following is a correct statement about the function of dendrites?

Accepted Answer

They receive electrical signals from other neurons

Question 20

Which of the following best describes the role of an interneuron?

Accepted Answer

It connects sensory and motor neurons within the CNS
