Sphenoid bone, placed in the central skull is a complex and single bone. The sphenoid bone is joined with almost all bones of the skull. Most of the base of the central skull consists of the sphenoid bone. Also, the sphenoid bone extends from the central skull base to the sides of the human skull structure. Left and right lesser wings of sphenoid bone form the prominent ridge’s lip and these wings like structure forms the boundary between the middle and anterior cranial fossae. Moreover, greater wings of this bone from the anterior floor of the middle cranial fossa extend either side away from the sella turcica.
