Neurons are composed of three main parts: dendrites, a cell body, and an axon. Signals are received through the dendrites, travel to the cell body, and continue down the axon until they reach the synapse (the communication point between two neurons).

They wrap around a part of the nerve cell called the axon, which helps messages move quickly and keeps the axon healthy. Some Schwann cells also provide support to smaller nerve cells without wrapping around them. They play a key role in our nervous system. By Matt Jensen.
