-
Pituitay gland
-Anterior lobe -
thyroid-stimulating horme
TSH - Stimulates thyroid gland to frow and produce thyroid hormone
- TSH
- Stimulates Adrenal cortex to secrete its hormones
-
Adrenocorticotropic hormone
ACTH - Stimulates ovarian follicles to mature & estrogen production
-
follicle-stimulating hormone
FSH - sperm producion
-
follicle-stimulating hormone
FSH - ovulation
-
luteinizing hormone
LH - testosterone secretion
-
Interstitial cell-stimulating hormone
ICSH - Promotes growth of all tissues
-
growth hormone or somatotropin
GH - Stimulates production of milk by breasts
- prolactin
-
Pituitary gland
_posterior lobe - ADH
- Promotes water reabsorption from kidneys to the blood
-
antidiuretic hormone
ADH -
Stimulates uterine contractions
stimulates release of milk from breasts - oxytocin
- Thyroid gland
- thyroid hormone or thyroxine
- Increases production of energy
- thyroid hormone or thyroxine
- Decreases blood calcium by inhibiting osteoclasts (decreases breakdown of bone
- Calcitonin
- Parathyroid gland
- PTH
- Increases blood calcium by stimulating osteoclasts to breakdown bone and by increasing Ca & P absorption in small intestines & kidneys
-
parathormone or parathyroid hormone
PTH - Increases gluconeogenesis for energy & conserves glucose for use by the brain, especially during stress: has an antiflammatory effect (blocks histamine)
-
glucocorticoids
(cortisol) - Increases NA reabsorption from kidneys to blood and K excretion by way of urine
-
Mineralocorticoids
(aldosterone) - Prolongs "fight or flight" response that is initiated by sympathetic nerves
-
epinephrine & norepinephrine
or adrenalin & noradrenalin - -Adrenal medulla
- ********
-
Increases blood glucose by increasing
glycogenolysis & gluconeogenesis - Glucagons
-
Pancreas
-Alpha cells of the islets of Langerhans - *
- -Beta cells of the islets of Langerhans
- *
- Decreases blood glucose by increasing transport of glucose into cell to be used for enrgy, increases storage of excess glucose as glycogen, increases transport of gatty acids and amino acids into cell
- Insulin
- Sex glands
- Ovaies
- Maturation of reproductive system, development of secondary sex characteristics, regulates menstrual cycle
- Estrogen
-
Sex glands
Ovaries - *
- Works with extrogen to establish menstrual cycle and plays a role in pregnancy
- Progesterone
- Testes
- *
- Maturation of reproductive system, development of secondary sex characteristics, sperm production
- testosterone
