It makes up most of the middle part of the base of the skull and contributes to the floor of the middle cranial fossa. The sphenoid bone consists of four parts: the body (corpus), the lesser and greater wings (alae minores et majores) and the pterygoid processes. The bone contains several important openings, such as the foramen rotundum (→ maxillary nerve) and the foramen ovale (→ mandibular nerve, accessory meningeal artery) and more. The body and lesser wings of the sphenoid bone mature through classic endochondral ossification, whereas the pterygoid processes undergo intramembranous ossification.
