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: -It helps form the base and lateral sides of the skull in combination with the orbital floor. Its many articulations with other bones give the skull rigidity. It is an attachment site for many of the muscles of mastication. A portion of the sphenoid forms the facial skeleton.
Detailed explanation-3: -The sphenoid bone of the skull base is one of the most complex bones of the body. It is an unpaired bone with many foramina (holes) and grooves that allow nerves and blood vessels to pass through or along it. The form of the sphenoid bone is often referred to as bat-shaped, wasp-shaped, or butterfly-shaped.
