endocrine system hormones

FSH

follicle stimulating hormone: stimulates growth and hormone production in the ovarian follicles of female, production of sperm in males

LH

luteinizing hormone (female): causes ovulation and secretion of progesterone in females

ICSH

interstitial cell-stimulating (male): stimulates testes to secrete testosterone.

GH

somatotropin

• Stimulates growth of most cells

• Regulates metabolism

TSH

thyrotropin

• stimulates growth

• stimulates thyroxine  from thyroid

ACTH

adrenocorticotropic

• Stimulates growth

• Increases in time of stress and increases cortisol (adrenal secretion)

PRL

prolactin

• Stimulates milk production in breast tissue (mammary glands)

LTH

lactogenic

• Stimulates milk production in breast tissue (mammary glands)

ADH

antidiuretic hormone (vasopressin)

• promotes reabsorption of water in kidneys, constricts blood vessels.

OT

Oxytocin (pitocin)

• Increases contractions of uterus during childbirth

• stimulates milk flow from the breasts.

• Estrogens

• stimulate female sexual characteristics 

Androgens

• stimulate male sexual characteristics

epinephrine

• activates sympathetic nervous system, acts in stress

norepinephrine

• activates body in stress situations 

PTH

• parathyroid hormone 

  • Regulates amount of calcium and phosphate in the blood. Increases reabsorption of calcium and phosphates from the bones

mineralocorticoids

(aldosterone) 

• regulate the reabsorption of sodium in the kidney and the elimination of potassium.

glucocorticoids

• cortisol-hydrocortisone, cortisone)

  • aid in metabolism of proteins, fats, and carbohydrates; increase amount of glucose in blood; provide resistance to stress; depress immune responses (anti-inflammatory)

thyrocalcitonin or calcitonin

accelerates absorption of calcium by the bones and lowers blood calcium level

thyroxine and triiodothronine

• increase metabolic rate

• stimulate physical and mental growth, regulate metabolism of carbohydrates, fats, and proteins

thymosin

timulates production of antibodies early in life

estrogen

• stimulates growth of reproductive organs

Progesterone

• maintains lining of uterus to provide fetal nutrition.

Testosterone

• stimulates growth and development of sex organs in the male

Melatonin

• may delay puberty by inhibiting gonadotropic (sex) hormones. May regulate sleep/wake cycles

Serotonin

• may prevent vasoconstriction of blood vessels in the brain
