Statement A : Myelinated nerve fibres are found in autonomous and the somatic neural systems. Statement B : Unmyelinated nerve fibres are found in spinal and cranial nerves.
1 Statement A is correct but Statement B is incorrect.

The myelin sheath is present in the
1 Dendrite
2 Cyton
3 Nodes of ranvier
4 None of them
Explanation:
Only medullated / myelinated neurons have axons with schwann cells and nodes of ranvier.

Myelin sheath is produced by:
1 Astrocytes and Schwann cells
2 Oligodendrocytes and Osteoclasts
3 Osteoclasts and Astrocytes
4 Schwann cells and Oligodendrocytes
Explanation:
Myelin is made by two different types of support cells. In the central nervous system (CNS) i.e., the brain and spinal cord cells called oligodendrocytes wrap their branch-like extensions around axons to create a myelin sheath. In the nerves outside of the spinal cord, Schwann cells produce myelin.
