Introduction[edit | edit source]

The anatomy of the canine spine is almost similar to the human spine. The spine of the canine also supports weight and encloses the spinal cord. The spine is located along the dorsal/top side of the canine's body and runs from the base of the head to the end of the tail. [1]

The canine spine is divided into five regions: cervical, thoracic, lumbar, sacral, and caudal. There are 7 cervical vertebrae, 13 thoracic vertebrae, 7 lumbar vertebrae, 3 sacral vertebrae and the number of caudal vertebrae varies according to the species.[2]

Cervical spine[edit | edit source]

Atlas and axis are the first two cervical vertebrae respectively.

The atlanto-occipital joint is a condylar modified synovial hinge joint. The capsule of the joint is strengthened by three thickenings: dorsal, ventral, and lateral.[3]The transverse process of the atlas is the wing that allows the articulation of the occipital condyles and the spine.The atlas and axis are fused in embryonic life.[2]The transverse atlantal ligament is the one that holds the dens of the axis against the ventral arch of the atlas. [3]

Axis is the second cervical vertebra and is the longest vertebra. The atlantoaxial joint is the pivot joint and has a loose joint capsule. The dens of the axis is connected to the occipital bone through the apical ligament.[3]
