| MSH released from | APG; corticotropes |
| MSH action | + melanocyte to produce skin pigment |
| Hormone: Follicle stimulating hormone FSH, triggered by: | GnRH |
| FSH released from | APG; gonadotropes |
| FSH action | + gamete maturation + spermatogenesis |
| Hormone: Lutenizing Hormone LH, triggered by | GnRH |
| LH released from | APG; gonadotropes |
| LH action | + production of testosteron + production of estrogen and progesterone |
| Hormone: Growth Hormone GH, triggered by | GnRH |
| GH released from | APG; somatotropes |
| GH action | direct action= + growth in kids +IGF released in liver |
| Hormones: Melatonin, triggered by | Sleep routine |
| Melatonin released from | Pineal Gland |
| Melatonin action | Induces sleep |
| Hormone: Throxine T4, triggered by | TSH |
| T4 released from | Thyroid |
| T4 action | Increase BMR |
| Hormone: Triiodothyronine T3, triggered by | TSH |
| T3 released from | Thyroid |
| T3 action | Increase BMR |
| Hormone: Calcitonin, triggered by | Increased CA# in blood |
| Calcitonin releaseed by | Thyroid |
| Calcitonin action | + CA# excretion by kidneys + CA# storage by bones |
| Hormone: Parathyroid Hormone PTH, triggered by | Decrease of CA# in blood |
| PTH released by | Parathyroid glands |
| PTH action | + CA# reabsorption by kidney + CA# release by bone + CA# absorption by GI |
| Hormone: Epinephrine,triggered by | flight or fight |
| Epi released by | Adrenal medulla |
| Epi action | Vasoconstriction GI Tract, reproduction, skin, hair, increase BV/BP |
| Hormone: Norepinephrine, triggered by | flight or fight |
| NorE released by | Adrenal Medulla |
| NorE action | Dilated pupils, increase heart rate. |
| Hormone: Aldosterone, triggered by | the RAAS cascade, decrease BP/BV |
| Aldosterone released by | Adrenal Cortex |
| Aldosterone action | + NA reabsorption by kidney |
| Hormone: Cortisol, triggered by | ACTH |
| Cortisol released by | Adrenal Cortex |
| Cortisol action | Increase blood GLU for CNS, + lipogenesis |
| Hormone: Glucagon, triggered by | Fasting/low levels of GLU, AA, and Fats in blood. |
| Glucagon released by | Pancreas |
| Glucagon action | Catabolic action- glycogenolysis, lipolysis, gluconeogenesis |
| Hormone: Insulin, triggered by | Eating/high levels of GLU, AA, and Fats in blood. |
| Insulin released by | Pancreas |
| Insulin action | Anabolic action= glycogenesis, lipogenesis, protein synthesis |
