Endocr. Syst Chart 3
Endocrine Hormones & Hormone Functions
Hormone | Hormone Function |
---|---|
Calcitonin | Decreases blood calcium levels by inhibiting osteoclasts |
Androgens | Insignificant in males; increases sex drive in females |
Glucagon | Increases blood glucose levels by stimulating liver to break down glycogen into glucose |
Follicle-stimulating hormone (FSH) | Stimulates sperm production. Stimulates oocyte production and estrogen secretion. |
Antidiuretic Hormone (ADH) | Decreases water lost in urine by returning water to the blood. |
Thymosin | Promotes the maturation of T cells for the immune response |
Progesterone | Stimulates development of female sex characteristics; helps regulate menstrual cycle |
Melatonin | Helps to set biological clock |
Luteinizing hormone (LH) | Stimulates secretion of testosterone. Triggers ovulation and stimulates secretion of estrogen and progesterone |
Norepinephrine (NE) | Promotes fight or flight response |
Thyroxine (T4) | Increases metabolism and basal metabolic rate (BMR) |
Cortisol | Increases resistance to stress, increases blood glucose levels, and decreases inflammation |
Epinephrine | Promotes fight or flight response |
Testosterone | Stimulates development of male sex characteristics; stimulates male sex drive; regulates sperm production |
Prolactin (PRL) | Stimulates production and secretion of milk |
Insulin | Decreases blood glucose levels by transporting glucose into body cells |
Melanocyte-stimulating hormone (MSH) | Darkens skin pigmentation |
Oxytocin (OT) | Stimulates uterine contractions and milk ejection during suckling. |
Adrenocorticotropic hormone (ACTH) | Stimulates secretion of hormones by adrenal cortex |
Aldosterone | Decreases sodium and water loss in urine by returning sodium and water to the blood |
Estrogen | Stimulates development of female sex characteristics; helps regulate menstrual cycle |
Thyroid-stimulating hormone (TSH) | Stimulates growth of thyroid gland and secretion of its hormones |
Triiodothyronine (T3) | Increases metabolism and BMR |
Parathyroid hormone (PTH) | Increases blood calcium levels by stimulating osteoclasts to break down bone matrix |
Human growth hormone (hGH) | Stimulates secretion of hormones that stimulate body growth and metabolism |
