While highly specialized and shaped differently, neurons share some of the basic cell structure as other cells in the body. They have a neuronal body or soma like other cells, but unlike others they have two types of extensions also called nerve fibers, dendrites and axons. Within the neuronal body is a nucleus and mitochondria surrounded by cytoplasm. The nucleus holds the information to run the cell’s growth and function. The mitochondria provide energy to the cell through the conversion of raw materials. The neuronal body is on average 0.0008 inches wide (Parker, 1997). Extending from the soma are treelike branches called dendrites. They are responsible for receiving is information and sending it to the cell body. One neuron may have more than 10,000 dendrites (Parker, 1997). The second type of neuronal body extension is the axon. It is a longer, thicker, single extension that may branch several times. Axons vary in size from a few inches to a few feet but are microscopically thin. Some are surrounded by a myelin sheath that keeps the electrical impulse traveling along the axon from leaking away and speeds up its transmission. Myelin is a white protective wrapping of glial cells called Schwann cells. Glial cells are nerve cells that protect and nourish the neurons. Occasional gaps called Ranvier nodes occur in the myelin. The end of the axon is called the terminal end (Farley et al., 2014).
