Sinus occipitalis

The video tutorial explains the role and anatomy of brain sinuses, focusing on the occipital sinus. It describes how venous blood is drained from the brain into the internal jugular vein, forming the brachiocephalic vein and eventually the superior vena cava. The brain sinuses are located intracranially and are unique in structure, lacking valves and not accompanied by arteries. The occipital sinus, one of the unpaired sinuses, runs along the cerebral sickle and connects with the vertebral venous plexus. The tutorial highlights the anatomical features and pathways of these sinuses.
