List of Hormones and their Functions
These are then carried by blood into target tissues where they show their effect.
They regulate most of the body physiology and functions.
These hormones if deficient or if excess can lead to hormonal disorders.
These can have a deleterious effect on the health and physiology.
So how many hormones are there in the human body?
Below is the comprehensive list along with their functions.
List of Hormones and their Functions in the human body
|Hormone||Function||Endocrine Gland secreting|
|Thyrotropin-releasing hormone (TRH)||Stimulates thyroid gland to synthesize T3 & T4 hormones||Hypothalamus (HYP)|
|Corticotropin-releasing hormone (CRH)||Stimuates cortex of adrenal gland to secreate gluco and mineralo corticoids||(HYP)|
|Growth hormone-releasing hormone (GHRH)||Stimulates formation of growth hormone,||(HYP)|
|Growth hormone inhibitory hormone (GHIH) (somatostatin)||Inhibits release of growth hormone, TSH, insulin||(HYP)|
|Gonadotropin-releasing hormone (GnRH) or leutinising hormone releasing hormone.||Controls release of FSH, LH||(HYP)|
|Dopamine or prolactin-inhibiting factor (PIF)||Inhibits prolactin secretion.||(HYP)|
|Growth hormone||Stimulates growth of the body||Anterior pituitary (AP)|
|Thyroid-stimulating hormone (TSH)||Releases T3 & T4||(AP)|
|Adrenocorticotropic hormone (ACTH)||Stimulates adrenal cortex to produce||(AP)|
|Prolactin||Stimulates milk formation||(AP)|
|Follicle-stimulating hormone (FSH)||Stimulates to form sperms in male and Ova in female.||(AP)|
|Luteinizing hormone (LH)||Formation of ova in females & production of testosterone||(AP)|
|Antidiuretic hormone (ADH) (also called vasopressin)||Limit water expulsion by kidney. It also constricts blood vessels and rise blood pressure||Posterior pituitary|
|Thyroxine (T4) and triiodothyronine (T3)||Regulates body metabolism and heat||Thyroid|
|Calcitonin||Reduces blood calcium. by enhanced deposition in bone, decrease in intestinal absorption and expulsion by kidney.||Thyroid|
|Cortisol||Increases blood sugar levels and supress immune system||Adrenal cortex|
|Norepinephrine, epinephrine||Adrenal medulla|
|Insulin (β cells)||Helps absorb glucose from blood to tissue and also release from liver||Pancreas|
|Glucagon (α cells)||Helps absorb glucose into liver to form glyocgen||Pancreas|
|Parathyroid hormone (PTH||Parathyroid|
|Testosterone||Builds muscles, give muscline character and also stimulate formation of sperms||Testes|
|Estrogens||Development of female reproductive system.||Ovaries & Placenta|
|Progesterone||Menstruation, Aids zygote implantation, Lactation & sexual drive||Ovaries & Placenta|
|Human chorionic gonadotropin (HCG)||Placenta|
|Renin||Helps maintain blood volume and there by blood pressure||Kidney|
|1,25-Dihydroxycholecalciferol||Rises Blood calcium levels||kidney/nephron|
|Erythropoietin||Stimulates formation of red blood cells.||Kidney|
|Atrial natriuretic peptide (ANP)||balance of water, sodium, potassium and fat in body||Heart muscle|
|Gastrin||To secrete gastric juice||Stomach|
|Secretin||Water levels and water balance in body||Small intestine/duodenum|
|Cholecystokinin (CCK)||Stimulates fat and protein digestion in intestine.|
|Leptin||Regulates energy balance. Inhibits hunger if needed||adipose cells|
|Ghrelin||Stimulates hunger||Gastro intestine|
