|
Oxytocin
|
Made by the hypothalamus, stored in the posterior pituitary. stimulates uterine contraction, and milk ejection.
|
|
|
ADH - antidiuretic hormone
|
Made by the hypothalamus, secreted by the posterior pituitary
Increases water retention and vasoconstriction [vasopressin]/^BP |
|
|
Releasing and Inhibiting hormones
|
A number of hormones secreted by the hypothalamus that stimulate or inhibit the anterior pituitary.
|
|
|
Growth Hormone GH
|
"Somatotropin"/Anterior Pituitary/ stimulates growth of bone, muscles, and tissues
|
|
|
Thyroid Stimulation Hormone TSH
|
"thyrotropin"/Anterior Pituitary/ stimulate thyroid
|
|
|
Adrenocorticotropic Hormone ACTH
|
anterior pituitary/stimulate adrenal cortex
|
|
|
Follicle-Stimulation Hormone FSH
|
anterior pituitary/Stimulate follicle to mature the egg, ovary to secrete estrogen//stimulate sperm production and testosterone
|
|
|
Prolactin
|
anterior pituitary/initiate and maintain lactation//decrease LH causing decreased testosterone
|
|
|
Luteinizing Hormone
|
anterior pituitary/ ovulation, prepare for milk secretion//stimulate testes to develop, ^testosterone
|
|
|
Anterior Pituitary
|
GH, TSH, ACTH, Prolactin, FSH, LH
|
|
|
Thyroid Hormone TH
triiodothyronine T3, thyroxine T4 |
Thyroid hormone, follicular cells/ controls metabolism
|
|
|
Calcitonin
|
Thyroid hormone, extrafollicular cells/deposits calcium in bones, increase Ca2+ secretion in urine (decrease serum Ca2+)
|
|
|
Parathyroid hormone
|
Parathyroid glands/increase serum Ca2+, decrease serum phosphate levels
|
|
|
Epinephrine
|
"adrenaline", adrenal medulla, fight or flight
|
|
|
Norepinephrine
|
"noradrenaline", adrenal medulla, fight or flight
|
|
|
Aldosterone
|
Adrenal cortex/zona glomerulosa, retain Na (water), decrease K
|
|
|
Renin
|
ENZYME! Kidneys -> zona glomerulosa, released when blood volume is decreased
|
|
|
Cortisol
|
Adrenal cortex/zona fasciculata, maintain serum glucose during stress
|
|
|
Sex hormones
|
Adrenal cortex/zona reticularis, develop sex organs, supplements sex hormones
|
|
|
Insulin
|
Pancreas/beta cells/islets of langerhans, lowers blood glucose levels
|
|
|
Glucagon
|
Pancreas/alpha cells/islets of langerhans, raise blood sugar
|
|
|
Somatostatin
|
Pancreas/delta cells/istlets of langerhans, inhibits release of glucagon and insulin
|
|
|
Thymosin
|
Thymus, inrease production of T-Lymphocytes
|
|
|
Testosterone
|
Testes, 2ndary sex characteristics, develop sex organs
|
|
|
Melatonin
|
Pineal Glad, delays reproductive development, regulates circadian rhythm
|
|
|
Estrogen
|
Mainly ovaries, female secondary sex characteristics, thickens endometrium
|
|
|
Progesterone
|
Ovary/corpus luteum (eggless follicle), vascularize endometrium, maintain pregnancy
|
|
|
Prostaglandins
|
Every cell -> neighboring cells, pain and inflammation
|
|
|
Enterocrinin
|
Small intestine, stimulate intestinal secretions after food enters
|
|
|
Gastrin
|
Stomach, increase gastric gland activity leading to the release of gastric juices
|
|
|
Erythropoietin
|
Kidneys, erythrocyte formation
|
|
|
ANP (atrial natriuretic peptide)
|
heart, increase Na+ secretion (and therefore water), decrease blood pressure.
