Final answer:
The sheet of dura mater located between the cerebellum and the cerebrum, which contains the transverse sinuses, is known as the tentorium cerebelli.
Step-by-step explanation:
The sheet of dura mater that lies between the cerebellum and the cerebrum and contains the transverse sinuses is called the tentorium cerebelli. This structure serves as a shelf-like formation that separates the occipital lobes of the cerebrum from the cerebellum.
It is one of the infoldings of the dura, which is a thick fibrous layer that provides a protective sheath over the entire brain and spinal cord. The dura mater also envelops and supports the venous sinuses, including the superior sagittal sinus and the transverse sinuses, which are crucial for draining blood from the central nervous system (CNS) to the jugular veins.
