Question

Unmyelinated nerve fibres enclosed by Schwann cells are commonly found in?

• A. Central neural system
• B. Somatic neural system
• C. Sympathetic neural system
• D. Both $\left(B\right)$ and $\left(C\right)$

Answer 1

The correct option is D Both $\left(B\right)$ and $\left(C\right)$

The myelinated nerve fibres are enveloped with Schwann cells, it form a myelin sheath around the axon.
Unmyelinated nerve fibres is enveloped by a Schwann cell that doesn't form a myelin sheath around the axon, and found in autonomous and the somatic neural systems. Sympathetic Nervous system is part of Autonomous Nervous system. Hence Option D is correct.
