Falx cerebri

The video tutorial provides an in-depth look at the dura mater, the outermost layer of the meninges that envelop the brain and spinal cord. It explains the structure of the dura mater, including its two layers and their attachment to the skull and brain contours. The tutorial also covers the formation of dura septa, particularly the largest one, the brain sickle, and its role in separating the brain's hemispheres. Additionally, the video discusses the venous sinuses formed by the dura mater, which are crucial for directing venous blood from the brain into the internal jugular vein.
