greater wing of sphenoid bone

(redirected from Great wing)

great·er wing of sphe·noid bone

(grā'tĕr wing sfē'noyd bōn)
Strong squamous processes extending in a broad superolateral curve from the body of the sphenoid bone. The greater wing presents these surfaces (facies): 1) cerebral surface forms anterior third of the floor of the lateral portion of the middle cranial fossa; 2) temporal surface forms the deepest portion of the temporal fossa; 3) infratemporal surface forms the "roof" of the infratemporal fossa; 4) orbital surface forms posterolateral wall of orbit. The greater wing forms the inferior border of the supraorbital fissure and is perforated at its root by the rotundum, ovale, and spinosum foramina and the pterygoid canal.
