GROSS ANATOMY

Detailed explanation-1: -The middle fossa is made up of the greater wings of the sphenoid bone and the temporal bone. It can be said to be butterfly shaped. It houses the pituitary gland and the two lateral parts of the fossa contain the temporal lobes.

Detailed explanation-2: -The pituitary gland or the hypophysis cerebri is a vital structure of the human body as it performs essential functions for sustaining life. It has the pseudonym of “the master gland.” The location of the gland is within the sella turcica of the sphenoid bone.

Detailed explanation-3: -– The Sphenoid bone (os sphenoidale; Gr., sphen – wedge + eidos – form) is a butterfly-shaped cranial bone that is located in the middle of the skull between the frontal and temporal bones.

Detailed explanation-4: -Shaped like a butterfly or a bat, it has a central body and two lateral wings on either side.

The articulations of the sphenoid are with the frontal, parietal, ethmoid, zygomatic, temporal, occipital, palatine, and vomer bones.

Detailed explanation-5: -The pituitary gland is located at the base of the brain, behind the bridge of the nose. It is about one-half inch (1.25 cm) in diameter. The pituitary gland rests within a hollowed out area of the sphenoid bone called the sella turcica.
