There are three components to the nerve cell. This includes a cell body, axon and dendrites. These components help send and receive chemical signals as well as electrical signals within different parts of the body which helps control a person’s activity. Nerve cells are important because they use signals to send and receive information to different parts of the brain and nervous system.
The first component is the cell body also known as soma which contains the nucleus. The soma role is to keep production of protein and energy to the axon. Axon is a major branching fiber that splits into branches and connects to cells that send information. Myelin sheath is formed around axons. This helps transmit electrical impulses quickly through neurons, muscles and glands. Dendrites are smaller branching fibers and functions. Dendrites is when nerve cells receive and process information from other cells. Neurons can receive numerous input cells thus the inhibitory signals will choose whether that neuron will fire, if so this nerve impulse is called action potential which is then sent to the axon.
