59, The First Cervical Vertebra, Atlas, superior view. 



The atlas consists of an anterior arch, a posterior arch, and 

 2 lateral masses, Massae laterales atlantis, formed at the point where the 

 arches unite ; it has no articular processes and no spinous process ; instead 

 of the articular processes there are superior grooved and inferior flat 

 articular surfaces. In the middle of the posterior surface of the anterior 

 arch lies the articular surface for the odontoid process of the second 

 cervical vertebra.
