Nerve cells are called neurons, they send and receive signals from the brain. While they have certain similarities with other cells such as a nucleus, cell body, and membrane, they are structurally and functionally unique. Neurons lie adjacent to one another but are not connected, the gap between them is called a synapse. The function of a neuron is to transmit the nerve impulses through the neuron, across the synapse to the next neuron.

Neurons can change depending on where they are located, but they each have three essential parts.
The soma (otherwise known as the cell body) maintains the structure of the neuron, contains genetic information, and provides energy. The soma contains the organelles and the nucleus (produces genetic information and directs the synthesis of proteins that are vital for other parts of the neuron to function), and it’s surrounded by a membrane that allows it to interact with its immediate surroundings while also protecting it.
The axon is a tail-like structure that is long and joins the cell body at the axon hillock. It’s a nerve fiber that conducts electrical impulses away from the soma. Axons are insulated with a myelin sheath which conducts electrical signals, it allows the nerve impulses to transmit more quicker. The myelin sheath prevents the impulse of one neuron from interacting with the impulse of another.
The dendrites are fibrous roots that look like antennae since they branch out of the soma. They receive and process the signals from the axons of other neurons, transmitting them toward the soma. They are usually shorter than the axons and more in number.
