- growth hormone
- prolactin
- Females: increase estrogen secretion; Males: increase spermatogenesis
- Females: increase progesterone secretion and oogenesis/ovulation; Males: increase testosterone secretion
- increase growth of thyroid and secretion of T3/T4
- increase growth of adrenal cortex and secretion of hormones
- increase growth and fat metabolism; increase blood sugar
- breast development and milk production by mammary glands
Posterior Pituitary (2 hormones)
- ADH (antidiuretic hormone)
- Oxytocin
Posterior Pituitary
What is the function of each:
-ADH (antidiuretic hormone)
-Oxytocin
- increase water reabsorption at DCT and collecting duct
- uterine contraction during childbirth; milk ejection during lactation
Pineal
secretion (1)
function (3)
Melatonin: biological clock; diurnal cycle (day/night); menstrual cycling
Thyroid (3 hormones)
- T4
- T3
- Calcitonin
Thyroid Function of each: -T4 -T3 -Calcitonin
- thyroxine precursor to T3
- triiodothyronine regulates cell metabolism and growth
- decrease blood Ca++ levels by promoting osteoblastic activity
Parathyroid (1)
abbreviation
function
-PTH
increase blood Ca++ levels by promoting osteoclastic activity and release of calcitriol (Vit D) from kidneys for increase gut absorption
Thymus
secretion (1)
function
Thymosin
development/maturation of T cells
Adrenals
Cortex (3)
- Mineralocorticoids (Aldosterone)
- Glucocorticoids (Cortisol)
- Weak Androgens (DHEA)
Adrenals Function of each: -Mineralocorticoids (Aldosterone) -Glucocorticoids (Cortisol) -Weak Androgens (DHEA)
- (SALTY) increase Na+ reabsorption from DCT/collecting duct; increase water retention
- (SWEET) stress response that increase blood glucose, increase fat metabolism, decrease immune/inflammation, decrease injury repair
- (SEX) weak steroidal sex hormones needed for sex development
Adrenals
Medulla:
Hormone (2)
Function
Epinephrine/Norepinephrine
- prolongs/enhances sympathetic response (increase fight or flight)
Pancreas (2 hormones)
Function
- Insulin: decrease blood sugar by putting glucose primarily into liver, muscles, fat cells
- Glucagon: increase blood sugar by releasing glycogen stores from liver and promoting gluconeogenesis (liver makes glucose from non-sugars)
Gonads
2 organ systems
Hormones (3)
Function
Testes
-Testosterone increase growth and maintenance of male sex organs/characteristics
Ovaries
- Estrogen: increase growth and maintenance of female sex organs/characteristics
- Progesterone: promotes growth of uterine lining
