Anterior clinoid process

Bone: Anterior clinoid process
Sphenoid bone. Upper and posterior surfaces. (Anterior clinoid process visible at top left.)

Latin	p. clinoideus anterior

In the sphenoid 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 of the groove for the internal carotid artery is converted into a foramen (carotico-clinoid).

Anterior clinoid process

Etymology

You may have noticed that the anterior and posterior clinoid processes surround the sella turcica like the four corners of a four poster bed. And that is what the word means. Cline is Greek for bed. –oid, as usual, indicates a similarity to. When you encounter clinical teaching, that implies teaching that is carried out at the bedside.

or it may comes from the Greek root klinein or the Latin clinare, both meaning "sloped" as in "inclined."
