=====Posterior clinoid process===== {{ https://upload.wikimedia.org/wikipedia/commons/d/db/Posterior_clinoid_process.jpg?500}} In the [[sphenoid bone]], the posterior boundary is formed by a square-shaped plate of bone, the [[dorsum sellae]] 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]]. see [[Posterior clinoid process meningioma]].
