Endocrine System- Hormone Function

Human Growth Hormone (HGH)

Stimulates secretion of hormones that stimulate body growth and metabolism

Thyroid-Stimulating Hormone (TSH)

Stimulates growth of thyroid gland and secretion of its hormones

Follicle-Stimulating Hormone (FSH)

Testes- Stimulates sperm production

Ovaries- Stimulates oocyte production and estrogen secretion

Luteinizing Hormone (LH)

Testes- Stimulates secretion of testosterone

Ovaries- Triggers ovulation and stimulates secretion of estrogen and progesterone

Prolactin (PRL)

Stimulates production and secretion of milk

Adrenocorticotropic Hormone (ACTH)

Stimulates of hormones by adrenal cortex

Melanocyte-stimulating Hormone (MSH)

Darkens skin pigmentation

Antidiuretic Hormone (ADH)

Decreases water lost in urine by returning water to the blood.

Oxytocin (OT)

Stimulates uterine contractions and milk ejection during suckling.

Thyroxine (T4)

Increases metabolism and basal metabolic rate (BMR).

Triiodothyronine (T3)

Increases metabolism and BMR

Calcitonin

Decreases blood calcium levels by inhibiting osteoclasts.

Parathyroid Hormone (PTH)

Increases blood calcium levels by stimulating osteoclasts to break down bone matrix.

Aldosterone

Decreases sodium and water loss in urine by returning sodium and water to the blood.

Cortisol

Increases resistance to stress, increases blood glucose levels, and decreases inflammation.

Androgens

insignificant in males; increases sex drive in females

Epinephrine

promotes fight or flight response

Norepinephrine (NE)

promotes fight or flight response.

Insulin

decreases blood glucose levels by transporting glucose into body cells

Glucagon

increases blood glucose levls by stimulating liver to break down glycogen into glucose.

Estrogen

stimulates development of female sex characteristics; helps regulate menstrual cycle

Progesterone

stimulates decelopment of female sex characteristics; helps regulate menstrual cycle

Testosterone

stimulates decelopment of male sex characteristics; stimulates male sex drive; regulates sperm production

Melatonin

helps set biological clock

Thymosin

Promotes the maturation of T cells for the immune response.
