Answer 1

The falx cerebri satisfies all the listed criteria by being a fold of dura mater, lying between the cerebral hemispheres, lying above the corpus callosum, and containing the superior and inferior sagittal sinuses. The answer is option E.

Step-by-step explanation:

The falx cerebri (e) all of these. This is because the falx cerebri is indeed a fold of the dura mater, which is the tough outermost layer covering the central nervous system. It also lies between the two cerebral hemispheres and above the corpus callosum, which is a thick fiber bundle that connects the hemispheres. Furthermore, it contains the superior and inferior sagittal sinuses, which are dural sinuses that drain blood from the majority of the outer cerebrum and allow cerebrospinal fluid to filter back into the blood for drainage.
