The C1 and C2 vertebrae are the first two vertebrae at the top of the cervical spine. Together they form the atlantoaxial joint, which is a pivot joint. The C1 sits atop and rotates around C2 below.

Nov 13, 2024 · C1 and C2 are the first two vertebrae at the upper part of the cervical spine. Together, they form a complex structure that supports the skull, known as the atlantoaxial joint. This structure also provides an optimal range of motion without compromising stability.

The C1 and C2 vertebrae function together to give your head flexibility. With the atlas and axis relationship, you are able to swivel and rotate your head, as well as support your head. These two vertebrae are more responsible for the head’s rotational range of motion than from any other joint.

By convention, the cervical vertebrae are numbered, with the first one (C1) closest to the skull and higher numbered vertebrae (C2–C7) proceeding away from the skull and down the spine. The general characteristics of the third through sixth cervical vertebrae are described here.
