Sinus sagittalis superior

The video tutorial explains the anatomy and function of brain sinuses, focusing on the superior sagittal sinus. Brain sinuses are venous channels that drain blood from the brain, skin, and eye cavity into the internal jugular vein. Unlike peripheral veins, brain sinuses lack vein flaps, allowing bidirectional blood flow. The superior sagittal sinus, one of the unpaired sinuses, is located in the fissura longitudinalis and runs along the cranial dome. It receives blood from superficial veins and cerebrospinal fluid from arachnoid villi, ultimately draining into the cardiovascular system.
