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 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 sphenoid bone is one of the seven bones that articulate to form the orbit. Its shape somewhat resembles that of a butterfly, bat or wasp with its wings extended.
The anterior clinoid process is a pyramid-shaped bony projection of the lesser wing of the sphenoid bone and forms part of the lateral wall of the optic canal. Between each ACP lies the sella turcica, which holds the pituitary gland. Additionally, the ACP is part of the anterior roof of the cavernous sinus. The posterior and inferior portions ...
A sphenoparietal sinus is situated under each lesser wing of the sphenoid bone near the posterior edge of this bone, [2] between the anterior cranial fossa and middle cranial fossa. [citation needed] It terminates by draining into the anterior part of the cavernous sinus. [2]
It is bounded in front by the posterior margins of the lesser wings of the sphenoid bone, the anterior clinoid processes, and the ridge forming the anterior margin of the chiasmatic groove; behind, by the superior angles of the petrous portions of the temporal bones and the dorsum sellae; laterally by the temporal squamae, sphenoidal angles of ...

"Comparing nutrition, bone-in wings tend to have more fat thanks to the skin, but they've got that rich flavor," said Ibrahim. "Boneless wings offer a consistent texture but can clock in higher on ...
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. Along the posterior part of the lateral margin of this groove, in the angle between the body and greater wing, is a ridge of bone, called the ...
