Answer:
It is tissue specialised in reception, integration and transmission of stimuli or impulses to various parts of the body.
the abilty to respond to stimuli is present in all living cells. however, integration and long distance rapid transmission of stimuli is possible with the help of nervousesystem only.
Nervous system is devoid of matrix. its cells are surrounded by special connective tissue cells.
Nervous tissue and its connective tissue cells aggregate to form brain, spinal cord, and nerves.
individual cells of nervous tissue are called nerve cells or neurons. they are the longest cell of the body reaching upto a metre in length.
each neuron is made up of two parts, cell body and neurites. neurites are of two types, dentrites and axons.
