principles anatomy I don't know Flashcards
Main endocrine glands
Hypothalamus parathyroid and thyroid adrenal pancreas ovaries testes
location of the pituitary gland
sits in pituitary fossa of sphenoid
connected to the hypothalamus by the infundibulum
division of the pituitary
anterior- hypothalamus stimulates release of hormones into the bloodstream. GH, prolactin, TSH, ACTH, LH, FSH
posterior (and hypothalamus)- oxytocin and vasopressin
vasopressin
ADH
Portal system
capillary bed between two set of veins
main purpose of the anterior lobe of the pituitary
controls hormone secretion from all the other glands
Where is the thyroid gland>
attached to the larynx .
purpose of the thyroid gland
uses iodine to manufacture triiodothyronine (essential for life) and thyroxine
parathyroid gland function
manufaacture parathyroid hormone. this controls calcium in bone and blood.
not under pituitary contrl.
cannot live without.
blood supply of thyroid and parathyroid glands
inferior artery comes off right subclavian.
superior thyroid artery comes off external carotid artery
compartment of the pancreas
retroperitoneum
division of the pancreas
endocrine - islets of langerhans
exocrine- digestive enzymes
2 adrenal glands
- adrenal cortex- glucocorticoids, mineralocorticoids, adrogens
- adrenal medulla- medulla, noradrenaline
blood supply to adrenal
suprarenal artery/ suprarenal vein (drains into renal)
