Anatomical terminology

The jugular foramen is a large foramen (aperture) in the base of the skull. It is located behind the carotid canal and is formed in front by the petrous portion of the temporal bone, and behind by the occipital bone; it is generally larger on the right than on the left side.

Contents

Cranial nerves IX, X, and XI and the internal jugular vein pass through the jugular foramen.
