Abstract
A hormone is a chemical substance released from a secretory cell that acts upon specific receptors present in another cell, to effect a physiological change in the function of the target cell. Endocrine action occurs in a distant organ, usually after transportation of the hormone through the circulatory system. A paracrine action is upon a cell adjacent to the secretory cell, and autocrine actions are upon receptors expressed by the hormone-secreting cell itself.
