Answer
The given figure shows a section of the Nerve.
A nerve refers to a bundle of axons (nerve fibres) enclosed in a tubular medullary sheath, that act as a pathway for transmitting information between the brain and other parts of the body, enabling sensation and movement.
The part "X" depicts Nerve fibres.
The protective, tubular covering is the Myelin Sheath.
Three kinds of nerves are:
- Sensory nerves
- Motor nerves
