Hope it will help uh...

Answer 2

Nervous Tissue

The tissue that receive stimulus and transmit it from one part of the tissue to other, are nervous tissues.The cells that constitute nervous tissue are called nerve cells or neuron. These are highly specialised for receiving stimulus and then transmitting it very rapidly from one place to another within the body itself. Brain, spinal cord and nerves are composed of nervous tissues. An individual nerve cell or a neuron may be upto a metre long and is composed of three major parts:

Cell body It consists of cytoplasm, nucleus and cell membrane.

Axon It is a single long conducting fibre extending from neuron. It transmits impulse away from the cell body.

Dendrites These are short branched fibres of neuron, which receive nerve impulses.
