TENTORIUM CEREBELLI Meaning and
Definition
-
The tentorium cerebelli is a double-folded, crescent-shaped structure found within the skull cavity that plays a crucial role in the division and support of the brain. It separates the cerebrum from the cerebellum, two major regions of the brain, and helps maintain the overall structural integrity of the cranium.
An anatomical landmark, the tentorium cerebelli is positioned horizontally within the skull, with its convex upper surface attached to the inner surface of the skull. It serves as a partition that separates the supratentorial space, containing the cerebral hemispheres, from the infratentorial space, housing the cerebellum. This bony structure also functions to support the weight of the occipital lobes and limits their downward displacement into the posterior cranial fossa.
Moreover, the tentorium cerebelli acts as a protective barrier by preventing the displacement of brain structures during sudden movements or traumatic events. Its strength and rigidity help shield the delicate cerebellum from potential damage, keeping it securely in place.
The tentorium cerebelli is richly vascularized, receiving blood supply from various arteries, including the anterior and posterior cerebral arteries. Furthermore, it contains several dural sinuses, such as the superior sagittal sinus and the straight sinus, which drain venous blood from the brain.
Overall, the tentorium cerebelli is a crucial anatomical structure that not only divides the brain but also provides support and protection for its major regions, ensuring the overall stability and normal functioning of the central nervous system.

A fold of dura mater roofing over the posterior cranial fossa and separating the cerebellum from the posterior portion of the cerebral hemispheres; it is attached along the middle line to the falx cerebri.

Etymology of TENTORIUM CEREBELLI
The word "tentorium cerebelli" is derived from Latin.
- "Tentorium" comes from the Latin word "tentorium", meaning "tent" or "awning". It refers to a structure in the brain that resembles a tent or a covering. The tentorium separates the cerebellum from the cerebrum, effectively forming a roof over the posterior cranial fossa.
- "Cerebelli" is the genitive form of "cerebellum", which is derived from the Latin words "cerebrum" (meaning "brain") and "bellus" (meaning "small"). Therefore, "cerebellum" can be translated as "small brain" and refers to the part of the brain responsible for motor coordination, balance, and posture.
