Assertion : Myelinated nerve fibre are enveloped with Schwan cells, which form a myelin sheath around the axon
Reason : Unmyelinated nerve fibre is not enclosed by a Schwan cell and hence does not form a myelin sheath around the axon.

A

If both assertion and reason are true and the reason is the correct explanation of the assertion.

B

If both assertion and reason are true but reason is not the correct explanation of the assertion.

C

If assertion is true but reason is false.

D

If both assertion and reason are false.

Text Solution

Verified by Experts

The correct Answer is:
C
The myelinated nerve fibres are enveloped with Schwann cells, which form a myelin sheath around the axon.
Unmyelinated nerve fibre is enclosed by a Schwann cell that does not form a myelin sheath around the axon, and is commonly found in autonomous and the somatic neural systems.
