The occipital like the other cranial the outer and inner tables between which is the cancellous tissue or diploë. Lateral jugular parts two. In the inferior fossæ it is thin semitransparent and destitute of diploë.

The basilar and condylar parts develop through endochondral ossification. It is one of seven bones that fuse together to form the skull and is directly next to five of the cranium bones. This curved bone contains the foramen magnum a large oval hole that allows the medulla oblongata to travel from the brain and connect to the vertebral canal.

The bone is especially thick at the ridges protuberances condyles and anterior part of the basilar part.
