Question

Given below the diagram of an axon. Label A to C correctly.

• A. A-Endoneurium, B-Neurolemma, C-Nucleus
• B. A-Neurolemma, B-Endoneurium, C-Schwann cell
• C. A-Node of Ranvier, B-Neurolemma, C-Schwann cell
• D. A-Neurolemma, B-Node of Ranvier, C-Schwann cell

Answer 1

The correct option is C A-Node of Ranvier, B-Neurolemma, C-Schwann cell

A-Node of Ranvier, B-Neurolemma, C-Schwann cell.
There are two types of axons, i.e., 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 sheath are called nodes of Ranvier.
