ANSWER...
The basic structural and functional unit of an nervous system is called neuron.
a neuron has three components:-
1. cyton - it is also called cell body. it have well defined nucleus. it has cytoplasm with nissl's granules or neurofibrils.
2. dendrites - it is a short thread like a structure arising from cyton. it receive impulse from outside and pass to cyton.
3. Axon - a long thread like a structure arising from cyton is called acon. it has fibrous branches at their and called axon ending. it conduct nerve impulse away from cyton. axon ending of one neuron are loosely placed on a cyton of other neuron.
NEURON HAS THREE TYPES:-
1. Sensory neuron - it carry message from body to brain.
2. Motor neuron - it carry message from brain to body.
3. mixed neuron - it carry message from body to brain and brain to body.
