| Description: Table 34.2 Primary Actions of Hormones Released Fro the Human Pit Pituitary Lobe Secretions Abbreviation Main Targets Primary Actions Posterior Antidiuretic hormone ADH Kidneys Induces water conservation as required to maintain Nervous tissue (vasopressin) extracellular fluid volume and solute concentrations (extension of , . . hypothalamus) Oxytocm OT Mammary glands induces mllk movement Into secretory ducts Uterus induces uterine contractions during childbirth Anterior Adrenocorticotropic ACTH Adrenal glands Stimulates release of cortisol, an adrenal steroid hormone Glandular hormone tissue, mostly Thyroid»stimulating TSH Thyroid gland Stimulates release of thyroid hormones hormone Follicle-stimulating FSH Ovaries, testes In females, stimulates estrogen secretion, egg maturation; hormone in males, helps stimulate sperm formation Luteinizing hormone LH Ovaries, testes In females, stimulates progesterone secretion, ovulation, corpus Iuteum formation; in males, stimulates testosterone secretion, sperm release Prolactin PRL Mammary glands Stimulates and sustains milk production Growth hormone GH Most cells Promotes growth in young; induces protein synthesis, (somatotropin) cell division; roles in glucose, protein metabolism in adults
