Vedclass · Answer

(D) The $atlas$ is the first cervical vertebra $(C1)$,which is ring-like and lacks a $centrum$ and a $neural$ $spine$.The $axis$ is the second cervical vertebra $(C2)$,which is characterized by a prominent peg-like projection called the $odontoid$ $process$ (or $dens$) that projects cranially from its $centrum$.This $odontoid$ $process$ acts as a pivot around which the $atlas$ (and the skull) rotates,allowing for the side-to-side movement of the head.Therefore,the $axis$ differs from the $atlas$ primarily due to the presence of the $odontoid$ $process$.
