Describe the structure of a neuron and explain the function of each of its major parts.

A neuron is a nervous system cell specialized in the communication and information processing between the nervous system and the various organs. It is present under different structures (multipolar, unipolar, bipolar ...). It consists of three main parts:

*A cell body also called soma, it is composed of the cytoplasm and the nucleus of the cell that contains the DNA to encode the proteins necessary for the function of the neuron.

*Tree extensions that are also called dendrites, its role is to receive information.

*A single axon with the ability to route information to other cells.
