Anatomical terms of bone

In the sphenoid bone, the anterior boundary of the sella turcica is completed by two small eminences, one on either side, called the anterior clinoid processes, while the posterior boundary is formed by a square-shaped plate of bone, the dorsum sellæ, ending at its superior angles in two tubercles, the posterior clinoid processes, the size and form of which vary considerably in different individuals. The posterior clinoid processes deepen the sella turcica, and give attachment to the tentorium cerebelli.

Posterior clinoid process

Etymology

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