Cell body

Explanation:

All neurons are made up of three parts: an axon, a cell body and dendrites.

The body of the cell or also called soma is the part of the neuronal cell that contains the nucleus and also specialized organelles.

Dendrites receive and process signals from the axons of other cells. They are are like roots that branch out from the cell body.

An axon is a long structure which extends from the body of the cell. Some axons are covered by a layer of myelin that allows the fast transmission of information.
