There are two broad classes of cells in the nervous system: neurons, which process information, and glia, which provide the neurons with mechanical and metabolic support. Three general categories of neurons are commonly recognized (Peters, Palay, & Webster, 1976). read more
Unipolar neurons are nerve cells that have one extension connected to the soma. These cells are often used in afferent nervous system function, which means that it involves the senses. Bipolar neurons are nerve cells that have two projections and are used in specialized sense detection, such as in smell and sight. read more
Nerves are a collection of neurons, which are the individual nerve cells. Nerves can be damaged by diabetes - known as neuropathy. A neuron has a soma (the cell body) which includes the cell nucleus, dendrites which conduct stimulation of the nerve, one or more axons which provide nerves with their length and axon terminals which transmit impulses to other nerves. read more
