Neurons are the functional units of the nervous system. The three main parts of a neuron are axon, dendrite, and cell body.

Functions of the three parts of a neuron :

Axon : It conducts messages away from the cell body.

Dendrite : It receives information from axon of another cell and conducts the messages towards the cell body.

Cell body : It contains nucleus, mitochondria, and other organelles. It is mainly concerned with the maintenance and growth.
