Dural Venous Sinuses | Superior Sagittal, Transverse, Sigmoid & Cavernous

For more cadaveric images and question banks, visit https://bootcamp.com/med-school In this video, we walk through the dural venous sinuses in order, starting with the superior and inferior sagittal sinuses, following blood flow to the straight sinus, confluence, transverse and sigmoid sinuses, and ending at the internal jugular vein. We also cover the role of arachnoid granulations in draining CSF into venous circulation, plus the unique features and clinical importance of the cavernous sinus. What you’ll learn: 1. Formation of sinuses by separation of dura mater layers 2. Superior & inferior sagittal sinuses within the falx cerebri 3. Straight sinus → confluence of sinuses → transverse → sigmoid sinus → internal jugular vein 4. Cavernous sinus anatomy, contents (cranial nerves III, IV, V1, V2, VI & internal carotid artery), and clinical importance 5. Arachnoid granulations & CSF drainage into venous sinuses 6. Clinical correlations: cavernous sinus thrombosis, venous drainage patterns, and how sinus occlusion affects the brain By the end of this video, you’ll understand how the venous sinuses and CSF pathways work together to maintain intracranial pressure and protect the brain. ⏱️Timestamps 0:00 – Intro 0:23 – What are dural venous sinuses?
