Cell body is a part of Neuron or nerve cell.


Neurons are the basic structural and functional unit of the nervous system. Neurons have two main parts : the cell body and the nerve fibers.The cell body (also known as the soma) is the spherical part of the neuron that contains the nucleus.

Parts of a neuron :


This nucleus is the control center of the cell. In the cytoplasm of the soma, there are mitochondria, Golgi bodies, lysosomes, and extensive rough endoplasmic reticulum (ER). In a neuron, the rough ER has granular structures referred to as Nissl bodies (this is where protein synthesis occurs).

The nerve fibers are of two types : dendrites and axons. Dendrites are short and branched, like the branches of trees. These are the
receptive areas of the neuron and a multipolar neuron will have many dendrites.

The axon is a long process or fiber that begins singly but may branch and at its end has many fine extensions called axon terminals that contact with dendrites of other neurons.
