In summary, the falx cerebri is more than a simple membrane; it is a foundational pillar of cranial architecture. It ensures the physical separation of the hemispheres while facilitating the complex drainage systems required for healthy brain function.
The falx cerebri is anchored to several bony landmarks of the skull. At its anterior end, it attaches to the of the ethmoid bone. Moving posteriorly, it arches upward and backward, following the internal midline of the skull vault. Its superior border is attached to the internal surface of the calvaria, while its inferior border is free and sits just above the corpus callosum. At its posterior base, it blends with the tentorium cerebelli , the horizontal fold of dura that separates the cerebrum from the cerebellum. Physiological Functions [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. In summary, the falx cerebri is more than
