Major Endocrine Glands
- PITUITARY
- anterior pituitary
(adenohypophysis)
- hormones
- growth hormone
- Target: most tissue
- response: increse tissue
growth
- thyroid STIMULATING
hormone (TSH)
- T: thyroid gland
- R: increase thyroid
hormone secretion
- Adrenocorticotropic
hormone (ACTH)
- T: Adrenal cortex
- R: Increase
glucocorticoid
hormone secretion
- follicle stimulating
hormone (FSH)
- T: gonads
- R: Follicle
maturation and
estrogen secretion
- R: sperm cell
production
- Luteneizing
Hormong (LH)
- T: gonads
- R: Ovulation and
progesterone
production
- R: testosterone synthesis
and support for sperm cell
production
- Prolactin
- T: Ovaries and
Mamary glands
- R: milk
producing
- Melanocyte
stimulting hormone
- T: melanocytes
in the skin
- R: Increased melanin
production in
melanocytes to make
the skin darker in color
- Posterior pituitary
(neurohypophysis)
- ADH
- increse water
reapsorbtion
- oxytocin
- increase uterus
contraction and
milk expulsion
- thyroid gland
- structure
- location: neck
- di depan trachea,
di bawah larynx
- T3 and T4
(thyroid follicles)
- increase metabolic
rate, for growth.
- calcitonin
(parafolicular
cells)
- bone; decrease blood
calcium levels.
- parathyroid gland
- parathyroid
hormone (PTH)
- increase blood
calcium levels
- bone; increase bone breakdown
- kidnyes; increase calcium reapsorbtion
- small intestine: increase calcium
absorption, increase vit. D synthesis
- adrenal glands
- adrenal cortex
- zona glomerulosa
- mineralocorticoid;
kidney --> aldosterone;
fluid and electrolyte balance
- ↑ sodium reabsorption,
potassium and hydrogen ions
excretion; ↑ water reabsorption
- zona fasciculata
- glucocorticoid;
cortisol
- ↑ glucose production; inhibit
immune response and
decreased inflammation
- zona reticularis
- androgens
- females: development
of some secondary sex
characteristics
- steroid based
- structure: di
atas kidneys
- adrenal medulla
- epinephrine and
norepinephrine
- preparation for
physical activity
- i.e. ↑ heart rate, blood
flow, blood glucose,
etc
- pancreas
- insulin; decrease
blood glucose levels
- ↑ uptake and use of
glucose and amino acids
- glucagon; ↑
blood glucose
- ↑ breakdown of glycogen;
release of glucose into the
circulatory system
