WitrynaTo make this differentiation might be thought of as semantic quibbling. Many types of cells can generate action potentials, for example oocytes, some gland cells, and even plant cells. Few cells have action potentials that propagate from a point of origin in the cell to a particular terminal site or sites. kyoto imperial palace wikipediaAn action potential occurs when the membrane potential of a specific cell location rapidly rises and falls. This depolarization then causes adjacent locations to similarly depolarize. Action potentials occur in several types of animal cells, called excitable cells, which include neurons, muscle cells, and in some plant cells. Certain endocrine cells such as pancreatic beta cells, and certain cells of the anterior pituitary gland are also excitable cells. kyoto japanese language training centerWitrynaAction potential definition, the change in electrical potential that occurs between the inside and outside of a nerve or muscle fiber when it is stimulated, serving to transmit nerve signals.
