Internal Occipital Protuberance

Internal occipital protuberance

The Internal Occipital Protuberance is a prominent anatomical feature located on the occipital bone of the human skull. It is a median protrusion that is part of the endocranium, the inner surface of the base of the skull.

Anatomy

The internal occipital protuberance is found at the posterior part of the endocranium, near the center of the occipital bone. It is the point of attachment for the falx cerebri, a sickle-shaped fold of the dura mater, the outermost layer of the meninges that cover the brain.

Clinical Significance

The internal occipital protuberance is a significant landmark in neurosurgery and radiology. It serves as a reference point for the transverse sinuses, which are major blood vessels that drain blood from the brain.
