Name the two smooth rounded protebeses of the crenium that articulate

1.	Name the two smooth rounded protebeses of the crenium that articulate with atlas vertebrate.
Answer» Markings of the Axis\xa0Bone:\tBody or centrum\xa0(Corpus vertebrae) is a cylindrical mass on anterior side of the vertebra. It articulates with body of the vertebra below (C3).\tOdontoid process\xa0or dens\xa0(Dens axis) is a prominent rounded superior projection from the body.\tThis tooth-like elevation serves a stable point around which the atlas bone rotates (Gr., odous, tooth).\tSuperior articular\xa0facet\xa0(Facies articularis superior) is a smooth, sightly convex surface that articulates with the inferior articular facet on the altas bone above (C1)The\xa0atlas\xa0is the first\xa0cervical vertebra\xa0and articulates with the occiput of the head and the\xa0axis\xa0(C2). It\xa0differs from the other cervical vertebrae\xa0in that it has no\xa0vertebral\xa0body and no spinous process. Instead, the\xa0atlas\xa0has lateral masses which are connected by an anterior and posterior arch.
