Question

In the structure of a human neuron, the nodes of Ranvier are present on (A) Spinal and cranial nerves (B) Myelinated and medullated neurons (C) Autonomic and somatic neural system (D) Both (A)and(C)

Schwann cells formmyel in sheath around axon. The gaps between two adjacent myelin sheath are called nodes of Ranvier. Myelinated or medullatednerve fibres are found in spinal and cranial nerves. Unmyelinated nerve fibresis commonly found in autonomous and the somatic neural system.
