Nerve cells are composed of three prominent parts, the cell body, where the nucleus is located, axons, and dendrites. Nerve cells are engaged to send electrical and chemical signals to the brain and body. Nerve cells are made up of nervous tissue. The components of the neurons each have a function to conjointly form one major function in the cell for the body.

Dendrites, which are the short branches that come off the cell body, are responsible for receiving and processing the information encountered. As dendrites receive a legion of signals due to the many branches coming off the cell body, the dendrites gather all the signals to decide if they will fire a nerve impulse (signal) into the axon. This is called action potential. The action potential is decided by excitatory and inhibitory signals.

Axons are the long branch that is connected to the axon hillock which stems off of the cell body. Axons are covered in myelin sheath. This sheath protects the axon and helps send electrical impulses from one neuron to another. The myelin sheath is connected to oligodendrocytes which help the reproduction of myelin sheath around the axon. The glial cells help regulate communication between neurons and regeneration of protection around the axons. The axons are known to have branches called the axon terminal and at the end of the branches, are synaptic end bulbs. The terminal is used to make contact with other nerve cells. The synaptic bulbs serve as neurotransmitters. These neurotransmitters allow for electrical signals to be transformed into chemical signals.

Nerve cells (neurons) turn out to play a significant role in the human body. Neurologically, these cells are able to retrieve information from different areas of the brain and the different nervous systems to create a response and signals to every part of the body. Without neurons, the body would have no sensory, motor, or interneuron functions. The damage in nerve cells could also lead to not having the functions previously mentioned.
