  1. function of growth hormone or somatotropin
    • affects all tissues
    • promotes protein anabolism (growth, tissue repair) and lipid mobilization and catabolism.
    • Produced by the anterior pituitary
  2. Function of thyroid-stimulating hormone (TSH)
    • target tissue: thyroid gland
    • function: stimulates synthesis and release of thyroid hormones, growth and function of thyroid gland
    • Produced by the anterior pituitary
  3. Function of adrenocorticotropic hormone (ACTH)
    • Target tissue: adrenal cortex
    • Functions: fosters growth of adrenal cortex; stimulates secretion of corticosteroids
    • Produced by the anterior pituitary
  4. function of follicle-stimulating hormone (FSH)
    • Target tissue: reproductive organs
    • Function: stimulates sex hormone secretion;reproductive ¬†organ growth, reproductive processes
    • Produced by the anterior pituitary
  5. Function of melanocyte-stimulating hormone (MSH)
    • Target tissue: melanocytes in skin
    • functions: increases melanin production in melanocytes to make skin darker in color
    • Produced by the anterior pituitary
  6. Function of prolactin:
    • Target tissue: ovary and mammary glands in females
    • Function: stimulates milk production in lactating women; increases response of LH and FSH; has unclear function in men
    • Produced by the anterior pituitary
  7. function of oxytocin:
    • target tissue: uterus; mammary glands
    • Function: stimulates milk secretion and uterine contractility
    • produced in the posterior pituitary
  8. function of antidiuretic hormone (ADH)
    • target tissue: renal tubules, vascular smooth muscle
    • Function: promotes reabsorption of water, vasoconstriction
    • produced by the posterior pituitary
  9. thyroxine (T4)
    • target tissue: all body tissues¬†
    • function precursor to Tx
    • produced by: thyroid
  10. triiodothyronine (T3)
    • target tissue: all body tissues
    • Function: regulates metabolic rate of all cells and processes of cell growth and tissue differentiation
    • produced by: thyroid
  11. calcitonin
    • target tissue: bone tissue
    • Function: regulates Ca and phosphorus blood levels; decreases serum Ca levels
    • produced by: thyroid
  12. parathyroid hormone (PTH) or parathormone
    • target tissue: bone, intestine, kidneys
    • Function: regulates Ca and Phosphorus blood levels; promotes bone demineralization and increases intestinal absorption of Ca; increases serum Ca levels.
  13. epinephrine (adrenaline)
    &
    norepinephrine
    • function: response to stress; enhances n prolongs effects of SNS
    • produced by: adrenal cortex
  14. corticosteroids (e.g cortisol, hydrocortisone)
    • all body tissues
    • function: promote metabolism, response to stress; antiinflammatory
    • produced by the adrenal cortex
  15. androgens (testosterone, androsterone)
    and estrogen
    • function: promotes masculinization in men; growth an sexual activity in women
    • produced by the adrenal cortex
