The Middle Cranial Fossa Each fossae accommodates a different part of the brain. The middle cranial fossa is located, as its name suggests, centrally in the cranial floor. It is said to be “butterfly shaped”, with a middle part accommodating the pituitary gland and two lateral parts accommodating the temporal lobes of the brain. The hypophysial fossa or pituitary fossa (seat of the saddle) sits in the middle of the sella trucica. 2  It is a depression in the body of the sphenoid, which holds the pituitary gland. 3  The dorsum sellae (back of the saddle) forms the posterior wall of the sella turcica.
