Anteriorly, the posterior cranial fossa is bounded by the dorsum sellae, posterior aspect of the body of sphenoid bone, and the basilar part of occipital bone/clivus. [2] Laterally, it is bounded by the petrous parts and mastoid parts of the temporal bones, and the lateral parts of occipital bone. [2]
English: Boundaries of the posterior cranial fossa (green) 1: Dorsum sellae of the sphenoid bone; 2: Superior borders of the petrous part of the temporal bone; 3: Groove for transverse sinus of the occipital bone
English: Boundaries of cranial fossae. 1: Sphenoidal limbus (anterior margin of the chiasmatic groove) 2: Posterior borders of the lesser wings of the sphenoid; 3: Dorsum sellae of the sphenoid bone; 4: Superior borders of the petrous part of the temporal bone; 5: Groove for transverse sinus of the occipital bone
A cranial fossa is formed by the floor of the cranial cavity. There are three distinct cranial fossae: [1] Anterior cranial fossa (fossa cranii anterior), housing the projecting frontal lobes of the brain [2] Middle cranial fossa (fossa cranii media), separated from the posterior fossa by the clivus and the petrous crest housing the temporal ...
posterior cranial fossa: hypoglossal canal: 2-hypoglossal nerve (XII) occipital: posterior cranial fossa: foramen magnum: 1: anterior and posterior spinal arteries, vertebral arteries: lowest part of medulla oblongata, three meninges, ascending spinal fibers of accessory nerve (XI) [3] occipital: posterior cranial fossa: condylar canal: 1
The base of skull, also known as the cranial base or the cranial floor, is the most inferior area of the skull. It is composed of the endocranium and the lower parts of the calvaria . Structure

The tentorium cerebelli divides the cranial cavity into two closed spaces which communicate with each other through the incisura tentorii. The larger anterior space includes the anterior and middle cranial fossas and lodges the cerebrum; the small posterior space— the posterior cranial fossa contains the cerebellum, the pons, and the medulla.
