Cruciform eminence
Definition[edit | edit source]
The cruciform eminence divides the deeply concave internal surface of the occipital bone into four fossae:
- The upper two fossae are called the cerebral fossae, are triangular and lodge the occipital lobes of the cerebrum.
- The lower two are called the cerebellar fossae, are quadrilateral and accommodate the hemispheres of the cerebellum.
Anatomy[edit | edit source]
The upper fossae are separated from the lower fossae by a groove for the transverse sinuses.
Internal occipital protruberence[edit | edit source]
At the point of intersection between all four fossae is the internal occipital protuberance.
Other names[edit | edit source]
It is also known as cruciate eminence.
