What is the major function of the neuron?

The major function of neuron is the transmission of nerve impulse.

Explanation:

Neurons or nerve cells are the electrically excitable cells that transmit information from one part of the body to another by transmitting nerve impulse. Neuron is the structural and functional unit of nervous system.

Sensory neurons carry nerve impulse from the receptor cell and transmit it to the brain. Inter neurons are present between sensory and motor neuron. Motor neurons carry information from the brain to the effector organ. Effector organ may be any muscles, glands or hormones.

Pass information by generating electric signals

Explanation:

Neurons are the fundamental unit of the nervous system. Neurons send information across the body through generation of electric signals called as action potential. There are basically three types of neurons

a) Sensory neurons which carry information from the sense organs in the form of impulse to the central nervous system (CNS)

b) Motor neurons - These carry information from the CNS to the body parts such as sense organs, muscles etc.

c) Interneurons - They are connecting neurons which are responsible for transferring information from one neuron to the other neuron.
