1. Chemical substances produced by the ENDOCRINE and other glands or cells and released into the bloodstream to act upon specific receptor sites in other parts of the body, so as to bring about various effects. Hormones are part of the control and feedback system of the body by which HOMEOSTASIS is achieved. The pituitary hormones are adrenocorticotropin, to prompt cortisone release from the adrenal cortex; follicle-stimulating and luteinizing hormones to produce sperm and egg maturation in the testis and ovary; prolactin for milk secretion in the breast; thyroid stimulating hormone for the thyroid; growth hormone for the bones and muscles; melanotropin for the pigment cells (melanocytes); and antidiuretic hormone for water reabsorption in the kidneys. Under these influences, each of the endocrine glands produces its own hormones.
