Gray's subject #189 814

The diaphragma sellae or sellar diaphragm is the circular fold of dura mater that almost completely roofs the fossa hypophyseos of the sella turcica of the sphenoid bone within the skull. It retains the pituitary gland in the fossa hypophyseos, with only the infundibulum of the pituitary gland passing through it. The sensory innervation or the diaphragma sellae is by the first division of the trigeminal nerve.
