Sinus rectus

The video tutorial explains the sinus rectus, a venous blood conductor in the brain, and its role in draining venous blood into the internal jugular vein. It describes the anatomy of brain sinuses, their intracranial and intra-dural location, and their unique features compared to peripheral veins, such as the absence of vein flaps. The sinus rectus runs along the brain's midline and connects with various tributaries, including the inferior sagittal sinus and the superior cerebral vein, before flowing into the confluence. The tutorial highlights the anatomical path and function of the sinus rectus and its significance in cerebral circulation.
