Major functions of Hormones




1. Estrogens

 Female sexual characteristics, menstrual cycle

2. Progestins Involved in menstrual cycle and maintenance of pregnancy.
3. Androgens Male sexual characteristics, spermatogenesis.
4. Glucocorticoids
Affect metabolism, suppress immune system
5. Mineralocorticoids
Maintenance of salt and water balance
6. Epinephrine Increase heart rate and blood pressure. 
Promotes glycogenolysis in liver and muscle and lipolysis in adipose   tissue.
7. NorepinephrineStimulates lipolysis in adipose tissue.
8. Calcitriol Promotes absorption of calcium from intestine, kidney and bone.
9. T3 and T4Promote general metabolic rate.
10. Calcitonin Lowers serum calcium, decrease calcium uptake by bone and kidney
11. PTH Increase serum calcium, promotes calcium release from bone.
12. ACTH Stimulates the release of adrenocorticosteroids.
13. FSH
(Follicle Stimulating Hormone)
Stimulates ovulation and estrogen synthesis in females.
Promotes spermatogenesis in males.
14. LH ( Stimulates synthesis of estrogens and progesterone and causes ovulation.
Promotes androgen synthesis by testes.
15. hCH Stimulates progesterone release from placenta.
16. TSH Promotes the release of thyroid hormones (T3,T4)
17. Growth hormone Promotes growth of the body.
18. Prolactin Growth of mammary glands and lactation.
19. ADH Promotes water reabsorption by kidney.
 20. Oxytocin Stimulates uterine contraction and milk ejection.
21. Glucagon Increases blood glucose level, stimulates glycogenolysis and lipolysis.
22. Insulin Lowers blood glucose level, promotes protein synthesis and lipogenesis.
23. TRH Promotes TSH release.
24. GnRH Stimulates release of FSH and LH.
25. Gastrin Stimulates gastric HCl and pepsinogen secretion.
26. CCK Stimulate contraction of gall bladder and secretion of pancreatic enzyme
