Articulation between odontoid process and atlas. (Lateral mass visible at left and right.)

The lateral masses are the most bulky and solid parts of the atlas, in order to support the weight of the head.

Each carries two articular facets, a superior and an inferior.

It is the origin of the obliquus capitis superior and the insertion of the obliquus capitis inferior.
