Description
The body of sphenoid bone is the hollow, cube-like, centrally located part of the bone. It is continuous;
—superolaterally with both the right and left lesser wings of sphenoid bone;
—laterally with both the right and left greater wings of sphenoid bone;
—inferolaterally with both the right and left pterygoid processes of sphenoid bone.
The body of sphenoid bone consists of:
—anterior, posterior and inferior surfaces;
—a single sphenoidal yoke, sella turcica, limbus, chiasmatic sulcus and ethmoidal spine;
—a pair of carotid sulci, sphenoidal lingulae, petrosal processes and sphenoidal sinuses;
—the anterior portion of the clivus.
The body of sphenoid bone:
—articulates with the vomer, ethmoid, occipital, temporal and palatine bones;
—contributes to the formation of the anterior and middle cranial fossae, the medial walls of both the right and left orbits, and both the right and left nasal cavities;
—contributes to the formation of the right and left optic canals, superior orbital fissures and foramina lacera.
