Detailed explanation-1: -C2, the axis, articulates superiorly with C1 by a unique bony structure called the dens or odontoid process. It projects up from the vertebral body and articulates with the atlas. The dens permit pivoting motion and allow a greater range of motion in rotating the head laterally.
Detailed explanation-2: -The pivot joint is exemplified by the joint between the atlas and the axis (first and second cervical vertebrae), directly under the skull, which allows for turning of the head from side to side.
