[s2e6] Falx — Cerebri

The falx cerebri is a key landmark in clinical neurology and radiology. Because it is a rigid structure, it can be involved in a life-threatening condition known as . This occurs when high intracranial pressure (caused by a tumor or hemorrhage) forces one hemisphere under the free edge of the falx, potentially compressing the anterior cerebral artery and leading to a stroke.

The is a large, crescent-shaped fold of the dura mater—the outermost and toughest layer of the meninges—that descends vertically into the longitudinal fissure between the two cerebral hemispheres. Named for its resemblance to a sickle (from the Latin falx ), it is a critical anatomical structure that provides mechanical stability and houses vital venous drainage pathways within the cranium.

Located along the free inferior margin, it eventually joins the great cerebral vein to form the straight sinus. Clinical Significance The falx cerebri is a key landmark in
