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:
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.
The model is made in Blender, which you can download for free but also comes in fbx and obj. If you need textures you can contact me and I will send them to you
