The atlas vertebra corresponds to which cervical level?

Explanation:
The atlas vertebra is the first cervical vertebra, called C1. It sits directly beneath the skull and forms the atlanto-occipital joint with the occipital bone, which lets the head nod up and down. Unlike other vertebrae, the atlas has no vertebral body, reflecting its specialized role at the top of the spine. The next cervical level below is the axis (C2), which carries the dens that enables rotation of the head. This topmost position and its distinctive structure make it clear that the atlas corresponds to the first cervical level.
