| The cranial part of the axial region of this sclerotome fuses with sclerotome segments of the first three occipital somites to form the basion of the basiocciput. |
| The tectorial membrane limits extension, while odontoid impaction on the basion limits flexion. |
| These include the opisthion, basion, clivus, hard palate, atlas, pedicle of axis, and tip of the odontoid process. |
| Improved relations between the ten nations of the River Nile Basion over the use of the Nile waters have led to closer cooperation by Egypt and East Africa in other areas. |
