Atlantoaxialgelenk
The atlantoaxial joint, known in German as "Atlantoaxialgelenk," is a pivotal articulation located between the first and second cervical vertebrae, namely the atlas (C1) and the axis (C2). This joint plays a crucial role in allowing rotational movement of the head, enabling actions such as turning the head from side to side.
Anatomically, the atlantoaxial joint consists of three articulations: two lateral atlantoaxial joints between the articular facets
Range of motion at the atlantoaxial joint is primarily rotational, allowing the head to turn approximately
The atlantoaxial joint is innervated by the cervical spinal nerves and supplied with blood through branches
Due to its importance in head movement and its proximity to the spinal cord and vertebral arteries,
