The inferior sagittal sinus (also known by the alternate term inferior longitudinal sinus), within the human head, is an area beneath the brain, which allows blood veins to span the area, from the center of the head towards the back. It drains (from the center of the brain) to the straight sinus (at the back of the head), then to the transverse sinuses. See diagram (at right): labeled in the brain as "SIN. SAGITTALIS INF." (for Latin: sinus sagittalis inferior).
The inferior sagittal sinus courses along the inferior border of the falx cerebri, superior to the corpus callosum.
It receives blood from the deep and medial aspects of the cerebral hemispheres and drains into the straight sinus.
