Answer 1

${\huge{\fbox{\color{aqua}{Answer :-}}}}$

The basic unit of communication in the nervous system is the nerve cell (neuron). Each nerve cell consists of the cell body, which includes the nucleus, a major branching fiber (axon) and numerous smaller branching fibers (dendrites). The myelin sheath is fatty material that covers, insulates and protects nerves of the brain and spinal cord.

Nerve cells are usually shaped like branched trees. From the round, pyramidal or spindle-shaped cell body, the dendrites branch out like the top of a tree and the single axon travels out like the trunk.

There are many type of neurons. They vary in size from 4 microns (. 004 mm) to 100 microns (. 1 mm) in diameter.
