What is the structure of neuron?

Neurons are the fundamental unit of the nervous system specialized to transmit information to different parts of the body.

A neuron varies in shape and size depending upon their function and location. All neurons have three different parts – dendrites, cell body and axon.

Parts of Neuron

Following are the different parts of a neuron:

Dendrites

These are branch-like structures that receive messages from other neurons and allow the transmission of messages to the cell body.

Cell Body

Each neuron has a cell body with a nucleus, golgi body, endoplasmic reticulum, mitochondria and other components.

Axon

Axon is a tube-like structure that carries electrical impulse from the cell body to the axon terminals that passes the impulse to another neuron.

Synapse

It is the chemical junction between the terminal of one neuron and dendrites of another neuron.
