  • All the cells in our body show a response to stimuli.
  • But the cells of the nervous tissue are the most specialized cells in this aspect.
  • They rapidly transmit the signal from the response from one part of the body to another.
  • The cells of the brain, spinal cord and nerves are included in nervous tissue.
  • Each cell of the nervous tissue is called a nerve cell or neuron.
  • When many nerve cells are connected with the help of connective tissue, it is known as nerve.
  • Structure of Neuron:
    • A neuron consists of two parts, cell body and cell projections.
    • The cell body has a nucleus and cytoplasm
    • The cell body is surrounded by hair-like projections. A single long projection is called an axon and many small projections are called dendrites.
    • A nerve cell is about one meter long.
  • The signals received from the nerves help to create a response to cause a movement with the help of a muscle.
  • For example, when we touch a hot surface, the brain gives the signal to the muscles of the hand through nerves to remove the hand.
  • It is possible to give a fast response due to rapid signal transmission by nerve cells.
