Quizplus · Accepted Answer

Excess CSF is removed from the subarachnoid space by arachnoid villi, which are small, finger-like projections of the arachnoid mater that extend into the dural sinuses. The CSF is absorbed into the bloodstream through the arachnoid villi. The other options (A, B, C, and E) are not involved in the removal of excess CSF from the subarachnoid space.
