The lateral surfaces of the body are united with the greater wings of the sphenoid and the medial pterygoid plates.. Above the attachment of each greater wing is a broad groove, curved something like the italic letter f; it lodges the internal carotid artery and the cavernous sinus, and is named the carotid sulcus.
The sphenoid bone [note 1] is an unpaired bone of the neurocranium.It is situated in the middle of the skull towards the front, in front of the basilar part of the occipital bone.
The greater wings of the sphenoid are two strong processes of bone, which arise from the sides of the body, and are curved upward, laterally, and backward; the posterior part of each projects as a triangular process that fits into the angle between the squamous and the petrous part of the temporal bone and presents at its apex a downward-directed process, the spine of sphenoid bone.
The lateral pterygoid plate of the sphenoid (or lateral lamina of pterygoid process) is broad, thin, and everted and forms the lateral part of a horseshoe like process that extends from the inferior aspect of the sphenoid bone, and serves as the origin of the lateral pterygoid muscle, which functions in allowing the mandible to move in a lateral and medial direction, or from side-to-side.
The anterior border is serrated for articulation with the frontal bone.. The posterior border, smooth and rounded, is received into the lateral fissure of the brain; the medial end of this border forms the anterior clinoid process, which gives attachment to the tentorium cerebelli; it is sometimes joined to the middle clinoid process by a spicule of bone, and when this occurs the termination ...
The anterior border forms the posterior boundary of the sphenopalatine notch. [1]The posterior border, serrated at the expense of the outer table, [citation needed] articulates with the vaginal process of the medial pterygoid plate of sphenoid bone.
