Sinus petrosus

The video tutorial explores the sinus petrosus, part of the dual sinus system, and its role in venous blood drainage from the brain and eye cavity. It explains the cerebral sinuses' structure, located within the skull, and their unique characteristics, such as the absence of flaps, allowing bidirectional blood flow. The tutorial details the superior and inferior petrosus sinuses, their pathways, and their function in draining venous blood from various brain regions and the inner ear, ultimately merging into the internal jugular vein.
