- attach to the sternum by fusing to the cartilage of the immediately superior rib
- Passageway for spinal nerves exiting the vertebral canal
- Primary function : support the head No body, pedicle, lamina, or spinous process
- Large, tall body that serves as a base for the upwardly projecting dens (odontoid process) Dens provides a rigid vertical axis of rotation for the atlas and head
- Largest of all cervical vertebrae Have many characteristics of thoracic vertebraeLarge transverse processes and spinous process
- Full costal facet superiorly that accepts the entire head of the 1rst rib- Demifacet inferiorly that accepts part of the head of the second rib - Spinous process is especially elongated and often as prominent as C7
- Connect vertebral body to posterior elements
- what happens if horner's syndrome is NOT accompanied by Wallenberg syndrome or a viral infection?
- Primary weight bearing structure of each vertebrae
- Transverse foramina (anterior to the exiting spinal nerve roots)- C3-6 typical vertebrae with identical features- The Atlas (C1), the Axis (C2), and C7 are atypical
- M. Longissimus capitis et cervicis
- Attachements sites for heads of ribs (costotransverse joints)
- protects the posterior aspect of the spinal cord
- Small rectangular bodies made of a relatively dense and strong cortical shell
- M. Longissimus lumborum et thoracis
