What are Nerve Cells?
Neurons are the cells that receive and transmit signals. ... Each neuron contains a nerve cell body with a nucleus and organelles such as mitochondria, endoplasmic reticulum, and Golgi apparatus. Branching off the nerve cell body are the dendrites, which act like tiny antennae picking up signals from other cells.

Neurons are excitable, which means they function by using electrical stimulation. Through this electrical message, known as an action potential, neurons are able to initiate action in the cells they target.

NEURON STRUCTURE

The nervous system contains two types of cells: neurons and neuroglial cells. Neurons are the cells that receive and transmit signals. The neuroglial cells are the support systems for the neurons — the neuroglial cells protect and nourish the neurons.

At the opposite end of the nerve cell body is the axon, which is a long, thin fiber with branches at the end that sends signals. The axon is insulated by a myelin sheath made up of segments called Schwann cells. Nerve impulses are received by the dendrites, travel down the branches of the dendrites to the nerve cell body, and are carried along the axon.

When the impulse reaches the branches at the end of the axon, it is transmitted to the next neuron. Impulses continue to be carried in this way until they reach their final destination
