Hormones

GnRH (gonadotropin-releasing hormone)

produced by: specialised nerve cells in hypothalamus of the brain
target: anterior pituitary gland
function: stimulates synthesis and secretion of LH and FSH

LH (luteinizing hormone)

produced by: gonadotropic cells of the anterior pituitary gland
target: ovaries and testes
function: stimulates ovulation and sex hormone release

FSH (follicle stimulating hormone)

produced by: gonadotropic cells of the anterior pituitary gland
target: sertoli cells within testes (males) and the granulosa cells of ovary (females)
function: stimulates development of eggs and sperm

GH (growth hormone)

produced by: anterior lobe of pituitary gland
target: liver, adipose tissue
function: stimulates the growth of essentially all tissues of the body, including bone

PRL (prolactin)

produced by: anterior pituitary gland
target: mammary gland
function: promotes milk production

TSH (thyroid stimulating hormone)

produced by: anterior pituitary
target: thyroid gland
function: regulates thyroid hormones

OCT (oxytocin)

produced by: posterior pituitary gland
target: uterus and mammary glands
function: stimulates milk secretion and uterine contractions

ADH (antidiuretic hormone)

produced by: posterior lobe of pituitary gland
target: tubular cells of kidneys
function: regulates and balances the amount of water in your blood

Melatonin

produced by: pineal gland
target: brain (Suprachiasmatic nuclei)
function: regulates sleep-wake cycles

TH (thyroid hormone)

produced by: thyroid gland
target: all cells (?)
function: stimulates metabolism

Calcitonin

produced by: thyroid gland
target: bones
function: lowers blood calcium levels

PTH (parathyroid hormone)

produced by: parathyroid glands
target: kidneys, skeletal system, and intestine
function: increases blood calcium

Thymosin

produced by: thymus gland
target: white blood cells
function: stimulates development of disease-fighting T cells (keep us healthy by attacking virus-infected or cancerous cells)

Insulin

produced by: beta cells in pancreas
target: liver
function: stimulates the liver and most other body cells to absorb glucose; reduces blood sugar

Glucagon

produced by: alpha cells in the pancreas
target: liver
function: stimulates conversion of stored glycogen (stored in the liver) to glucose, which can be released into the bloodstream

Cortisol

produced by: adrenal gland
target: all cells (?)
function: resistance to stress, increases blood glucose levels

Aldosterone

produced by: adrenal gland
target: kidney
function: affects the body's ability to regulate blood pressure

Epinephrine

produced by: adrenal glands
target: muscles and blood vessels
function: increase cardiac output; raise glucose levels in the blood

Norepinephrine

produced by: adrenal glands
target: muscles and blood vessels
function: increases blood pressure and heart rate; constricts blood vessels

Estrogen

produced by: ovaries
target: female reproductive system
function: causes sexual development and growth; maintains proper functioning of female reproductive system

Progesterone

produced by: ovaries
target: mammary glands, uterus
function: prepares uterus for pregnancy

Testosterone

produced by: testes
target: throughout body
function: causes sexual development and growth spurt; maintains proper functioning of male reproductive system

Androgen

produced by: adrenal gland
target: gonads, skin, muscles and bone
function: crucial for male sexual and reproductive function (males), converted into the female hormones called estrogens (females)
