The brain is housed inside of a bony covering called the cranium. After passing through the CNS, blood returns to the circulation through a series of dural sinuses and veins (Figure 14.2.2).The superior sagittal sinus runs in the groove of the longitudinal fissure, where it absorbs CSF from the meninges.
