Examples
- The tentorium is a fold of dura mater that separates the cerebrum from the cerebellum and brainstem in the cranial cavity.
- The occipital lobes of the cerebrum rest on the tentorium, which supports them and prevents damage from movement of the cerebellum.
- Damage to the tentorium can cause compression of the occipital lobes, leading to vision problems and other neurological symptoms.
- Surgery to relieve increased intracranial pressure may involve incising the tentorium to allow for expansion of the brain tissue.
- The tentorium is attached to the posterior clinoid processes and the superior margin of the transverse sinus, forming a strong and stable fold of dura mater.
