In other cells, such as gland cells and ciliated cells, it is believed that the membrane voltage is important to the execution of cell function. The origin of the membrane voltage is the same in nerve cells as in muscle cells. In both cell types, the membrane generates an impulse as a consequence of excitation.This impulse propagates in both cell types in the same manner. What follows is a short introduction to the anatomy and physiology of nerve cells.2) numerous short processes of the soma, called the dendrites; and, (3) the single long nerve fiber, the axon. These are described in Figure 2.1. The body of a nerve cell (see also (Schad and Ford, 1973)) is similar to that of all other cells.
