Schwan cells are found in

Options

A. Myelinated nerve fibres
B. Unmyelinated nerve fibres
C. Both A and B
D. None of the above

Answer

C

Explanation

There are two types of axons, namely, myelinated and non-myelinated.
The myelinated nerve fibres are enveloped with Schwann cells, which form a myelin sheath around the axon.
The gaps between two adjacent myelin sheaths are called nodes of Ranvier.
Unmylinated nerve fibre is enclosed by a Schwann cell that does not form a myelin sheath around the axon.
