stimulates the adrenal cortex to secrete cortisol

These receptors may be intracellular or located on the plasma membrane.

Target cells must have specific receptors to which the hormone binds.Circulate to all tissues but only activate cells referred to as target cells.Have lag times ranging from seconds to hours.Regulate the metabolic function of other cells.Are chemical substances secreted by cells into the extracellular fluids.The nervous system can override normal endocrine controls The nervous system modifies the stimulation of endocrine glands and their negative feedback mechanisms. hypothalamus) and in turn, certain hormones can stimulate or inhibit the flow of nerve impulses. Note, however that these two systems coordinate their activities: certain parts of the nervous system stimulate or inhibit the release of hormones (e.g. Hormone can travel to another nearby cell or it can act on another part of the body. Other tissues and organs also produce hormones – adipose cells, cells of the small intestine, stomach, kidneys, and heart.Gonads (produce both hormones and exocrine products).Pancreas (produces both hormones and exocrine products).Hypothalamus (has both neural functions and releases hormones).Controls, maintains and instigates sexual reproduction, including gametogenesis, coitus, fertilization, fetal growth and development and nourishment of the newborn.Integrates and regulates growth and development.Maintains the internal environment in the body (the optimum biochemical environment).The endocrine system is made up of ductless glands called endocrine glands that secrete chemical messengers called hormones into the bloodstream or in the extracellular fluid.Ī hormone is a chemical substance made and secreted by one cell that travels through the circulatory system or the extracellular fluid to affect the activities of cells in another part of the body or another nearby cell.
