After completing this study unit you will be able to:
- Locate and name each cervical vertebra.
- Identify the bony landmarks and articular surfaces of the cervical vertebrae.
The cervical spine consists of seven vertebrae named sequentially in a superoinferior direction, C1-C7.
There are three atypical vertebrae in the cervical spine. The first (C1) and second (C2) cervical vertebrae are known as the atlas and axis, while the seventh vertebra (C7) is named the vertebra prominens, due its elongated spinous process. The rest of the cervical vertebrae, C3-C6, all have a similar anatomical structure and are therefore classified as typical vertebrae.

Now that you are familiar with each vertebra, let’s take a look at the associated joints and ligaments of the cervical spine.
Seven cervical vertebrae
Atypical: C1, C2, C7
|Typical vertebra||Body, arch (pedicles and laminae), spinous process, transverse processes, superior and inferior articular processes and their articular facets|
Atlas (C1): Anterior arch, posterior arch, lateral mass, transverse process, vertebral canal
Axis (C2): Vertebral body, dens axis, pedicle (x2), transverse process (x2), lamina (x2), spinous process
Vertebra prominens (C7): All features as in typical vertebra, except that the spinous process is longer and not bifid and the body is larger
