Cavernous sinus

The video tutorial explores the cavernous sinus, a key component of the dural venous sinuses responsible for venous drainage in the brain. It explains the structure and function of dural venous sinuses, highlighting their role in blood drainage from the brain to the internal jugular vein. The cavernous sinus, located on either side of the sphenoid bone, is unique for its communication between paired sinuses. It facilitates the passage of several cranial nerves and the internal carotid artery. The video also details the complex venous drainage of the cavernous sinus, involving the superior petrosal sinus and other pathways.
