Sphenoid bone

January 2017


Definition

Often compared to the shape of a bat or butterfly, the sphenoid bone is part of the orbital and nasal cavities of the skull and the skull base. This unique bone has a central body to which the following extensions are attached: the pterygoid and small and large wings. Thus, the central body of the sphenoid bone has six faces: the upper face, lower face, front face, rear face, and two side faces.
