Document Summary
The functions of the endocrine system: maintenance of the internal environment (body temperature, body fluid. Slower actions; more widespread thoughout the body volume, osmolality: adaptation to stress, control of growth and metabolism, control of reproduction. Endocrine gland: a group of specialized cells that synthesize, store, and release a very special chemical into blood (hormone). The hormone is released into the bloodstream and circulates throughout the body to specific target cells that have receptors for the hormone. The hormone will then have its effect on the target cell and can either stimulate or inhibit the activity of the cell. Physiology notes: module 13: hormones derived from the amino acid. Hormones are secreted into the blood in pulses by a very specific stimulus (neural or blood-borne) (amounts that vary with the strength of the stimulus) They exert their specific effects by binding to receptors on or in the target cells and generally act by regulating pre-existing reactions.
