Question

Which of the following is true about neurolemma

a. It is the outermost layer of the myelin sheath that has a nucleus & cytoplasm in oligodendrocytes
b. It is the outermost layer of the myelin sheath that has a nucleus & cytoplasm in schwann cells
c. It helps in repair of minimally damaged nerves, in the peripheral nervous system cells
d. a and c only
e. b and e only

Answer 1

The correct answer will be option- B.

Step-by-step explanation:

Neurolemma is the surrounding cells of the Schwann cells which cover the myelin sheath formed by the Schwann cells in the peripheral nervous system or PNS. These cells are absent in the central nervous system.

The neurolemma cells are the nucleated cells with cytoplasm which helps in the protection of the neurons as can regenerate the minimally damaged neurons if the cell body of the neurolemma is not damaged.

Thus, option- B is the correct answer.
