Endocrine Organs
Anterior Pituitary
-
-
Growth hormone (GH)
- stimulates release of IGFs from liver, which synergistically act on all body tissues, especially cartilage, bone, muscle, and adipose connective tissue to stimulate growth
Luteinizing hormone (LH)
- act on gonads to stimulate development of gametes and release hormones
-
Prolactin (PRL)
- in females, regulates mammary gland growth and milk production
- in males, may influence sensitivity of interstitial cells in testes to the effects of luteninizing hormone for testosterone secretion
-
Posterior Pituitary
-
Oxytocin (OT)
- in females, stimulates smooth muscle contraction in uterine wall and stimulates milk ejection from mammary glands
- in males, stimulates contraction of smooth muscle of male reproductive tract
Thyroid Gland
Calcitonin (CT)
- in bone and kidney, reduces calcium levels in body fluids
- decreases bone resorption by osteoclasts and increases calcium loss through kidneys
Thyroid hormone (TH)
- in most body cells, increases metabolism, oxygen use, growth, and energy use
- supports and increases rate of development
Adrenal Medulla
Epinephrine (E)
- both in various cells throughout the body
Norepinephrine (NE)
- both work with the sympathetic division of the ANS to stimulate fight-or-flight response
-
Adrenal Cortex
Corticosteroids
- Mineralocorticoids: kidney cells, regulate electrolyte composition and concentration in body fluids
- Glucocorticoids: liver cells, stimulate lipid and protein metabolism; regulate blood glucose levels
- Gonadocorticoids: sex organs, protein synthesis in sex organ cells
Pineal Gland
Melatonin
- makes us drowsy
- increases at night, decreases during the day
- helps regulate circadian rhythm
