A neuron (also called neurone or nerve cell) is a cell that carries electrical impulses. Neurons are the basic ( functional & structural ) units of our nervous system. Every neuron is made of a cell body (also called soma), dendrites and an axon. ... Neurons are connected to one another and tissues.

★ A neuron is a microscopic structure composed of three major parts, namely, cell body, dendrites and axon.
★ The dendrites are the short fibres which project out of the cell body and transmit impulses towards the cell body.
★ The axon is a long fibre that transmits nerve impulses away from the cell body to a synapse or to a neuro-muscular junction.
★ The three main parts of a neuron are the axon, dendrite, and cell body.
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.
★ Neurons are the basic building blocks of the nervous system. They are specialized for the conduction of nerve impulses in the body.
