PLAY
pineal
What gland secretes melatonin?
pineal
Body internal clock/circadian rhythm
hypothalamus
What gland secretes ADH(anti-diuretic hormone) and Oxytocin?
ADH (anti-diuretic hormone)
decreases urine output
Oxytocin
responsible for uterus contraction for labor & releasing milk
Pituitary
What gland secretes TSH, ACTH, FSH, LH, GH and PH?
TSH (thyroid stimulating H)
stimulates secretion of hormones from thyroid follicular cell
ACTH (adrenocorticotropic H)
secretion of glucotinius & growth of adrenal gland
FSH (follicle-stimulating H)
Ovarian follicle growth, estrogen secretion/sperm production
LH (luteinizing H)
Ovarian follicle growth, estrogen & progesterone secretion.....testosterone secret
GH (growth H)
stimulates growth
PH (prolactin)
breast development & secretion of milk
pineal, hypothalamus, pituitary
What 3 glands are in the head?
thyroid and parathyroid
What 2 glands are in the neck & throat?
PTH (parathyroid)
Increases blood calcium concentration
Thyroid
T3(triidothyronine) T4(tetraiodothyronine--forms C cells & Calcitonin
Calcitonin
decreases blood calcium concentration
Pancreas
What gland is in the abdominal/pelvic area?
Pancreas
Alpha & Beta cells
Glucagon
Alpha cells
Insulin
Beta cells
Glucagon
Increases blood glucose level
Insulin
Decreases blood glucose level
Thymus
What gland is in the Mediastine area?
Thymus
secretes thymosin
white blood cells
What are T&B cells?
Thymosin
produces T&B cells
ovaries
secrete estrogen & progesterone
estrogen
responsible for breast contour & growth, menstrual cycle
progesterone
prepares the uterus for pregnancy
testes
secrete testosterone
testosterone
responsible for beard, voice change, muscles and maturation of external genitals
adrenal
What glands are on top of the kidneys?
MC (mineralocorticoids)
increase blood sodium, decrease potassium
outer layer
What layer of the adrenal gland is the mineralocorticoids?
GC (glucocorticoids)
breaks down proteins & fats stored and converts them into glucose for an energy source
middle layer
What layer of the adrenal gland is the glucocorticoids?
Epinephrine/Non-Epinephrine
Prolongs the effects of the sympathetic stimulation--fight or flight response
inner layer
what layer of the adrenal gland is the Epinephrine/Non-Epinephrine?
Epinephrine
Adrenal medulla hormone that increases blood pressure by stimulating vasoconstriction during a stress response
Anti-diuretic hormone
Posterior pituitary hormone that decreases urine output by stimulating the kidneys to reabsorb weater, preventing dehydration
Adrenocorticotropic
Anterior pituitary hormone that regulates the endocrine activity of the adrenal cortex
growth
Anterior pituitary hormone that stimulates protein synthesis for muscle/bone growth and maintenance
progesterone
Prepares the endomedtrium for pregnancy
hormones
secretions of the endocrine system; chemical messengers
