Bone: Posterior arch
First cervical vertebra, or atlas. (Poster. arch labeled at bottom center.)
Latin	arcus posterior atlantis
Gray's	subject #21 99

In a cervical vertebra, the posterior arch forms about two-fifths of the circumference of the ring: it ends behind in the posterior tubercle, which is the rudiment of a spinous process and gives origin to the Recti capitis posteriores minores.
