endocrine hap 1 Flashcards
pineal gland
- location- brain
- hormones- melatonin-involved in biological rythms (daily and seasonal)
anterior pituitary
- location-brain
- hormones- growth hormone (GH), prolactin (PRL), follicle stimulating hormone (FSH), Lutenizing hormone (LH), Thyroid stimulating hormone (THS), Adrenocorticotropic (ACTH)
growth hormone (GH)
stimulates growth of muscles, bones and metabolism. (AP)
prolactin (PRL)
stimulates milk production (AP)
follicle stimulating hormone (FSH)
stimulates production of ova and sperm (AP)
Lutenizing hormone (LH)
stimulates ova (egg release) and testes (AP)
Thyroid stimulating hormone (THS)
stimulates thyroid gland (AP)
Adrenocorticotropic (ACTH)
stimuates adrenal cortex to secrete glucocortoids (AP)
posterior pituitary
- location
- hormones- oxytocin-stim contraction of uterus and ‘let down’ of milk.
- anti-diuretic hormone-promotes retention of water by kidneys
thyroid gland
location-neck
- hormones- thyroid hormone, calctonin
- thyroid hormone-stimulates metabolism
- calcitonin- reduces blood calcium levels
parathyroid gland
location-neck
-hormones-parathyroid hormone- raises blood calcium levels
adrenal glands/ medulla
location-kidney
hormones-epinephrine/ nonepinephrine- raise blood glucose level
adrenal cortex
location- kidney
hormones-glucocorticoids, mineralocorticoids, gonadocorticoids
glucocorticoids- adrenal cortex
increase blood glucose
mineralocorticoids- adrenal cortex
increase re-absorption of of Na+ and excretion of K+
