Location of hypothalamus
Below thalamus, and near optic chiasm
Structure in diencephalon (3)
thalamus, hypothalamus, and pineal gland
Location and product of pineal gland
below corpus callosum, produces melatonin
Location of pituitary gland
within hypophyseal fossa in sphenoid bone
What surrounds pituitary gland?
Diaphragma sellae, meningeal dura fold
Anterior pituitary also known as …
adenohypophysis
Posterior pituitary also known as …
neurohypophysis
What arteries supply pituitary glad?
ant.= superior hypophyseal a.
post.= inferior hypophyseal a.
both come from internal carotid a.
Where do hyophyseal veins drain into?
Cavernous sinus, sup. & inf. petrosal sinuses
sup. –> tras, sigmoid
inf. –> sigmoid, internal jugular v.
Function of parathyroid
regulation of Calcium
Arteries that supply thyroid
- sup. thyroid a. from external carotid a.
- inf. thyroid a. from thyrocervical branch
- thyroid ima a. (rare)
Where do thyroid veins drain into?
sup. and middle thyroid vv. drain into IJV
L & R inf. thyroid vv. drain into LEFT brachiocephalic v.
