The atlas bone is the first of seven cervical vertebrae (vertebra cervicalis I or C1). It supports the weight of the skull. The name for the bone was derived from a deity of Greek mythology called Atlas, who supported the heavens.Markings of the Atlas Bone:

1. Lateral mass (Massa lateralis atlantis) is the thickest part of the bone. This sturdy region supports the weight of the skull.

2.Superior articular facet (Facies articularis superior) is an oval-shaped, concave structure on the superior aspect of the lateral mass. It articulates with an occipital condyle on the underside skull.

3.Inferior articular facet (Facies articularis inferior) is a flattened surface on the inferior lateral mass tht articulates with the superior articular facet on the axis vertebra (C2).

4.Transverse process (Processus transversus) is a prominent lateral projection from the lateral mass. It serves as an attacment site for muscles that move the head and neck.

5.Transverse foramen (Foramen transversarium) is a hole in the transverse process that serves as a passageway for the vertebral artery and vein.

6.Vertebral (spinal) foramen (Foramen vertebrale) is a large opening in the center of the bone through which the spinal cord passes.
