Answer:

nervous tissue is a tissue which is specialized to transmit messages within our body. brain, the spinal cord, and the nerves all are composed of nervous tissue.  they contain highly specialized unit, cells called neurons. neurons have the ability to receive stimuli from within or outside the body to conduct impulses to different parts of the body.

each neuron has three parts-

1. the cyton or cell body which contains a central nucleus and cytoplasm with characteristic deeply stained particles called nissl's  granules.
2. the dendrons which are short processes arising from the cyton and further branching into dendrites and
3. the axon which is a single , long cylindrical process of uniform diameter. it forms the fine branches terminally. each twig-like branch of axon ends in a swollen structure, called synaptic knob or bouton. bouton contains acetylcholine filled vessels (its an important neurotransmitter ). axon is alsocalled nerve fibre.
