The superior sagittal sinus is a large venous channel located in the brain. It runs along the midline of the skull, from the front to the back, and is situated between the two layers of the dura mater, which is the outermost protective covering of the brain. This sinus collects blood from the brain's surface and drains it into the transverse sinuses. This sinus plays a crucial role in the brain's venous drainage system. It receives blood from various smaller veins, including those from the cerebral cortex and the falx cerebri. The superior sagittal sinus ultimately helps return deoxygenated blood to the heart, maintaining proper blood circulation in the body.
