The vertebral column, also known as the spinal column, consists of 33 bones including 7 cervical, 12 thoracic, 5 lumbar, 5 sacral, and 4 coccyx vertebrae. The anatomy of C1 and C2, also known as the atlas and axis, are unique, but the anatomical features of the rest of the vertebrae are similar including the body, vertebral foramen, transverse processes, spinous process, pedicles, lamina, superior articular process, and inferior articular process.
