Secretion - Pituitary Lobe/Source, (Designation), Main Targets: Primary Actions
Antidiuretic hormone
Posterior, ADH, Kidneys: Induces water conservation as required during control of extracellular fluid volume and solute concentrations
Posterior, OCT, Mammary glands: Induces milk movement into secretory ducts, Uterus: Induces uterine contractions
Anterior, ACTH, Adrenal cortex: Stimulates release of cortisol, an adrenal steroid hormone
Anterior, TSH, Thyroid gland: Stimulates release of thyroid hormones
Follicle-stimulating hormone
Anterior, FSH, Ovaries, testes: In females, stimulates estrogen secretion, egg maturation; in males, helps stimulate sperm formation
Luteinizing hormone
Anterior, LH, Ovaries, testes: In females, stimulates progesterone secretion, ovulation, corpus luteum formation; in males, stimulates testosterone secretion; sperm release
Anterior, PRL, Mammary glands: Stimulates and sustains milk production
Somatotropin (or growth hormone)
Anterior, STH (GH), Most cells: Promotes growth in young; induces protein synthesis, cell division; roles in glucose, protein metabolism in adults
Melanocyte-stimulating hormone
Intermediate, MSH, Pigmented cells in skin and other integuments: Induces color changes in response to external stimuli; affects some behaviors
Glucocorticoids (including cortisol)
Adrenal Cortex, Most cells: Promote protein breakdown and conversion to glucose
Mineralocorticoids (including aldosterone)
Adrenal Cortex, Kidney: Promote sodium reabsorption (sodium conservation); help control the body's salt-water balance
Epinephrine (adrenaline)
Adrenal Medulla, Liver, muscle, adipose tissue: Raises blood level of sugar, fatty acids; increases heart rate and force of contraction
Adrenal Medulla, Smooth muscles of blood vessels: Promotes constriction or dilation of certain blood vessels; thus helps control the flow of blood volume to different body regions
Triiodothyronine, thyroxine
Thyroid, Most cells: Regulate metabolism; have roles in growth, development
Thyroid, Bone: Lowers calcium level in blood
Parathyroid hormone
Parathyroids, Bone, kidney: Elevates calcium level in blood
Androgens (including testosterone)
Gonads - Testes (in males), General: Required in sperm formation, development of genitals, maintenance of sexual traits; growth, development
Gonads - Ovaries (in females), General: required for egg maturation and release; preparation of uterine lining for pregnancy and its maintenance in pregnancy; genital development; maintenance of sexual traits; growth, development
Gonads - Ovaries (in females), Uterus, breasts: Prepares, maintains uterine lining fro pregnancy; stimulates development of breast tissues
Pancreatic Islets, Liver, muscle, adipose tissue: lowers sugar level in blood
Pancreatic Islets, Liver: Raises sugar level in blood
Pancreatic Islets, Insulin-secreting cells: Inhibits digestion of nutrients, hence their absorption from gut
Thymosins, etc.
Thymus, Lymphocytes: Have roles in immune responses
Pineal, Gonads (indirectly): Influences daily biorhythms, seasonal sexual activity
Gastrin, secretin, etc.
Stomach, Small Intestine, Stomach, pancreas, gallbladder: Stimulates activities of stomach, panceas, liver, gallbladder required for food digestion, absorption
Liver, Most cells: Stimulate cell growth and development
Kidneys, Bone marrow: Stimulates red blood cell production
Kidneys, Adrenal cortex, arterioles: Helps control secretion of aldosterone (hence sodium reabsorption, and blood pressure)
1,25-hydroxyvitamin D6 (calcitriol)
Kidneys, Bone, gut: Enhances calcium reabsorption from bone and calcium absorption from gut
Atrial natriuretic hormone
Heart, Kidney blood vessels: Increases sodium excretion; lowers blood pressure
