		Medial to this is a triangular, serrated surface, for articulation with the frontal bone; this surface is continuous medially with the sharp edge, which forms the lower boundary of the superior orbital fissure, and laterally with the serrated margin for articulation with the zygomatic bone.
		—The anterior border is serrated for articulation with the frontal bone.
		On the under surface of the vaginal process is a furrow, which is converted into a canal by the sphenoidal process of the palatine bone, for the transmission of the pharyngeal branch of the internal maxillary artery and the pharyngeal nerve from the sphenopalatine ganglion.

		As a reminder, the pterygoid is a dermal bone; and the alisphenoid is retreaded epipterygoid which traces its ultimate origin to the palatoquadrate and the gill arch series.
		The sphenoid thus incorporates derivatives of all three embryonic skull tissues: the endochondral bone of the neurocranium, the dermal bones of the palate, and gill arches.
		The ventral surface of the sphenoid body bears a triangular spine along the midline, the sphenoidal rostrum, which is continuous with the sphenoidal crest on the anterior surface, and articulates with a deep fissure between the wings of the vomer.

	eMedicine - Meningioma, Sphenoid Wing : Article Excerpt by: Sally B Zachariah, MD
		Anterior clinoid (medial sphenoid wing) meningiomas are a subcategory of the sphenoid wing meningiomas; they fall into 1 of 3 categories, according to the presence of an interfacing arachnoidal membrane between the tumor and the cerebral vessels.
		The relative incidence of meningiomas of the sphenoid ridge is 17%.
		Sphenoid wing meningiomas, or ridge meningiomas, are the most common of the basal meningiomas.

		Your cranial bones are not unbalanced, but their asymmetrical structural alignment can cause difficulties for the function of the brain and nervous system as well as the musculoskeletal structure.
		The bones are in their stable, asymmetrical alignment pattern because of the body's reaction to the physical, biochemical and emotional traumas it has been subjected to.
		The sphenoid bone is the strongest, the most difficult to get manual contact with, the most difficult to move, the most resistant to change.
