Neuron is the structural and functional unit of nervous system.

Neurons are irregular in shape and able to conduct electrochemical signals. Each neuron consists of dendrites, axon, soma and cell body.

2. The long extension of the cell body of the nerve cell is called as axon that serves to conduct the nerve impulse away from the cell body.
