Study Notes
Characteristics of Cervical Vertebrae
- The upper six cervical vertebrae have transverse processes with a unique feature: they possess foramina (holes) for the passage of the vertebral artery and vein.
- The cervical vertebrae, except for C7, have transverse processes that are short and bifid (split into two parts).
Articular Facets Orientation
- In the middle and lower cervical spine (C2-C3 to C7-T1), the articular facet joints are oriented in a transverse plane, aiding movement and flexibility.
Function of Anterior and Posterior Tubercles
- The anterior and posterior tubercles on the typical transverse processes serve as attachment sites for muscles and ligaments, contributing to the stability and mobility of the cervical spine.
Luschka Joint
- The cervical spine features Luschka joints (uncinate processes), which are located between the uncinate processes of adjacent vertebrae, providing stability and facilitating movement between cervical segments.
