What term describes the area above the tentorium where the cerebrum is located?

• A. Infratentorial
• B. Supratentorial
• C. Dural Folds
• D. Choroid Plexus Structures

Answer: (B)

The area above the tentorium cerebelli is called the supratentorial compartment. The tentorium is a horizontal dural fold that separates the cerebrum from the cerebellum and brainstem; anything located above this boundary—the cerebral hemispheres and related structures—is described as supratentorial. This contrasts with infratentorial, which refers to the region below the tentorium, including the brainstem and cerebellum. The other terms don’t describe a regional division: dural folds are the folds of dura mater itself, and choroid plexus structures are specific components within the ventricles that produce cerebrospinal fluid.
