Internal occipital crest
Internal Occipital Crest
The Internal Occipital Crest is a prominent anatomical feature found within the human skull. It is a ridge that extends along the internal surface of the occipital bone, from the Foramen magnum to the Internal occipital protuberance.
Anatomy[edit]
The Internal Occipital Crest is a bony ridge that divides the floor of the posterior cranial fossa into two halves. It serves as a point of attachment for the falx cerebri, a sickle-shaped fold of the dura mater that descends vertically in the longitudinal fissure between the cerebral hemispheres.
Function[edit]
The primary function of the Internal Occipital Crest is to provide support and attachment for the falx cerebri. This helps to stabilize the brain within the skull and prevent excessive movement, particularly during rapid head movements or trauma.
Clinical Significance[edit]
Due to its location and role in brain support, damage to the Internal Occipital Crest can potentially lead to neurological issues. However, such instances are relatively rare.
