-
Releasing and Inhibiting hormones
Located in hypothalamus. Reg secretion of pituitary hormones
-
Growth Hormone
Located in anterior pituitary gland. Essential for growth, stimulates bone and soft tissue growth, reg protein, lipid & carbohydrate metabolism
-
Adrenocorticotropic hormone (ACTH)
Located in anterior pituitary gland. Stimulates glucocorticoid secretion by adrenal cortex.
-
Thyroid Stimulating Hormone (TSH)
Anterior pituitary gland. Stimulates secretion of thyroid hormones by thyroid gland.
-
Prolactin
Anterior pituitary gland. Stimulates dev of breasts and milk secretion in females
-
Follicle stimulating hormone (FSH)
- Females: stim growth/dev of of ovarian follicles, estrogen secretion
- Males: stim testosterone secretion
Anterior Pituitary Gland
-
Luteneinizing Hormone (LH)
- Females: stimulates ovulation, trans of overian follicle into corpus leteum and secretion of estrogen and progesterone.
- males: stimulates testosterone secretion
- Anterior pituitary gland
-
Antidiuretic hormone (ADH/vassopressin)
- Posterior pituitary gland.
- Decreases urine output by kidneys, promotes constriction of blood vessels.
-
Oxytocin
- Posterior pituitary gland.
- Females: stim uterine contractions and milk ej
- Males: func unknown
-
Melatonin
Pineal gland. Reg biological day/night cycles.
-
Thymosin
Thymus. Stim proliferation (growth/dev) and func of T lymphocytes.
-
Thyroid Hormones (triiodothyronine and tetraiodothyronine)
Thyroid gland. Increase basal metabolic rate.
-
Calcitonin
Thyroid gland. Promotes calcium deposition in bone. Lowers blood calcium lvls
-
Parathyroid hormone (PTH)
- Promotes calcium release from bone, calcium absorption by intestine, and calcium reabsorption by kidney tubules. Raises blood calcium lvls. Stim vit d3 synthesis.
- Parathyroid gland.
-
Mineralcorticoids (aldosterone)
- Stim sodium reabsorption and potassium secretion by kidney tubules
- Adrenal cortex
-
Glucocorticoids (cortisol, corticosterone)
- promote catabolism of proteins/fats; raise blood glucose, adapt body to stress.
- Adrenal cortex.
-
Androgens
Adrenal cortex. promote sex drive
-
Epinephrine
Adrenal Medulla. Stim fight or flight
-
Insulin
Pancreas. Lowers blood glucose lvls, stores NRG by promoting protein, lipid, glycogen synthesis
-
Glucagon
Pancreas. Raises blood glucose lvls. mobilizes NRG by promoting glycogenolysis, gluconeogenesis
-
Somatostatin
Pancreas. Inhibits secretion of pancreatic hormones, reg dig and absorp of nutrients of GI system
-
Andgrogens (testosterone, androstenedione)
Testes. Sperm prod. Sex drive. Secondary sex char.
-
Estrogens (estradiol)
Necessary for follicular dev, secondary sex char. Ovaries
-
Progestins (progesterone)
Promote endometrial growth to prepare uterus for pregnancy. Ovaries
-
Chorionic gonandotrophin, estrogens & progesterone
Placenta (during preg). Maintain corpus luteum, reinforce action of hormones secreted by corpus luteum.
