Question restatement: Which dural septum separates the cerebral hemispheres?

Options to consider:
- Cavernous sinus
- Sellar diaphragm
- Tentorium cerebelli
- Falx cerebri
- Falx cerebelli

Analysis of each option:
- Cavernous sinus: This is a venous channel located on either side of the pituitary gland, forming part of the cavernous sinus system. It is not a dural partition between the cerebral hemispheres, so it does not separate the hemispheres.
- Sellar diaphragm: The diaphragma sellae is a small dura mater fold that roofs the sella turcica housing the pituitary. Its primary role is to cover the pituitary stalk and the pituitary itself, not to separate the cerebral hemispheres.
- Tentorium cerebelli: This structure is a horizontal dural fold that separates the cerebellum from the inferior portion of the occipital lobes (the supratentorial from the infratentorial compartments). It divides the cerebrum and cerebellum rather than the two cerebral hemispheres themselves.
- Falx cerebri: This is the vertical dural partition that runs along the longitudinal fissure, effectively separating the left and right cerebral hemispheres. It is the classic septum between the hemispheres.
- Falx cerebelli: This is a dural fold that separates the two cerebellar hemispheres along the posterior cranial fossa. It does not separate the cerebral hemispheres.

In summary, among the listed structures, the falx cerebri is the true dural septum that divides the cerebral hemispheres. The other options correspond to separations or coverings in different brain regions or compartments, not the hemispheric division.
