What anchors the meninges in the skull?

The meninges are anchored in the skull primarily by the dura mater, which is the outermost layer. This tough, fibrous membrane is attached to the inner surface of the skull, providing stability. Additionally, the dura mater has extensions, such as the falx cerebri and tentorium cerebelli, that help secure the brain within the cranial cavity. These structural features ensure that the meninges remain properly positioned to protect the brain.
