Inferior sagittal sinus

This tutorial explores the inferior sagittal sinus, a dural venous sinus involved in draining deoxygenated blood from the brain. It highlights the brain's high oxygen demand and its blood supply systems, the internal carotid and vertebrobasilar systems. The venous drainage system, including the dural venous sinuses and their connection to the internal jugular vein, is explained. The anatomy and location of the sagittal sinuses, particularly the inferior sagittal sinus, are detailed. The course and tributaries of the inferior sagittal sinus are also covered. The video concludes by promoting Kenhub as a resource for further anatomy learning.

What is the significance of the inferior sagittal sinus in terms of oxygen demand in the brain?

Explain how the venous drainage of the brain differs from its arterial supply.
