PPT-Mousa Tuwati Alfakhri Anatomy Pituitary

Anatomy Pituitary gland is enclosed in sella turcica and bridged over by fold of dura mater called diaphragma sellae with sphenoidal air sinuses below and optic chiasm above The cavernous sinuses . The pituitary gland lies within the sella connected to the brain above (the hypothalamus) by the pituitary stalk or infundibulum. The pituitary gland sits just above the sphenoid sinus and between Digital Laboratory. It’s best to view this in . Slide Show . mode, especially for the quizzes..
