Carotid groove

From Wikipedia, the free encyclopedia

Bone: Carotid groove
Sphenoid bone. Upper surface. (Carotid groove visible at left center.)
Base of the skull. Upper surface. (Sphenoid bone is in yellow, and carotid groove is labeled at center of sphenoid.
Latin	sulcus caroticus ossis sphenoidalis
Gray's	subject #35 148
Dorlands / Elsevier	g_12/12402464

Above the attachment of each great wing of the sphenoid bone 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 groove.
