![]() ![]() It also allows for blood supply to the brain through the passage of the vertebral artery. This cervical unit also facilitated a protective aspect of the spinal cord from external compression. In general, it stabilizes the head supports the weight in a neutral position. ![]() The function of this joint in the cervical spine is multifaceted. Without the atlantoaxial joint, the kinematic capability of the head and neck would not allow for the nearly 600 movements per hour that we make as humans. The multipurpose function of the atlantoaxial joint is crucial in practical application, allowing the head to rotate and turn to the left or right. This joint is unique among the rest of the cervical spine due to its lack of an intervertebral disk. As they reside in the craniovertebral junction at the convergence of the skull and the cervical spine, these two vertebrae are unique among the rest of the cervical spine due to their specific anatomical structure. ![]() The uppermost parts of the cervical spine that make up the atlantoaxial joint are the atlas (C1) and the axis (C2). The two bilateral atlantoaxial joints found laterally are classified as gliding joints. These structures are the osteoligamentous rings of the atlas and the transverse ligament, respectively. The median atlantoaxial joint's structure is formed by the dens of C1 vertebrae and two ligamentous structures anteriorly and posteriorly. It consists of three distinct, synovial joints: one medial joint and two lateral atlantoaxial joints. The atlantoaxial joint is a unique joint with multiple distinct structural aspects contributing to its crucial function for cervical stability and mobilization. ![]()
