Anatomical terms of bone

The middle clinoid process is a small, bilaterally paired elevation on either side of the tuberculum sellae, at the anterior boundary of the sella turcica. A (larger) anterior clinoid process is situated lateral to each middle clinoid process.[1]: 509  The diaphragma sellae (i.e. the dura forming the roof of the cavernous sinus)[1]: 443  and the dura of the floor of the hypophyseal fossa (sella turcica)[1]: 441  attach onto the middle clinoid processes.

On each side of the body, the internal carotid artery passes between the anterior and middle clinoid processes.[1]: 509 

Etymology

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