In which anatomical region can the atlas and axis be located?

The atlas and axis are the first two cervical vertebrae in the human spine, located in the cervical region. The atlas, known as C1, supports the skull and allows for the nodding motion of the head, while the axis, or C2, enables the rotational movement of the head by providing a pivot point for the atlas. This unique arrangement of vertebrae is critical for the mobility and flexibility of the neck. The cervical region is specifically designed to accommodate these vital functions, making it the correct anatomical location for the atlas and axis.
