The atlas, the uppermost cervical vertebra in the human spine, plays a vital role in supporting and connecting to the skull. It forms a pivot joint with the second cervical vertebra, known as the axis, enabling the atlas to rotate and facilitate the turning of the head from side to side. This pivotal mechanism grants us the ability to engage in lateral head movements.
The initial neck vertebra that supports the head.
