Internal occipital crest

Crista occipitalis interna

Definition

The internal occipital crest is a bony ridge located on internal surface of the squamous part of the occipital bone. It runs down the middle, starting from the internal occipital protuberance and stretching all the way to the posterior margin of the foramen magnum. This crest offers attachment to the falx cerebelli, a dural venous partition that separates the two cerebellar hemispheres from each other.
