week 7 Spinal Movements Continued........

Movements of the spine are possible due to intervertebral discs, and with the fulcrum of movement occurring primarily around the nucleus pulposus. Specialized motion occurs at the atlanto-occipital and atlantoaxial joints, which do not contain a disc.

The spine (vertebral column) forms the central axis of the skeleton, supports the skull, and gives attachment to the thoracic cage, pectoral girdle, and upper limb. It combines strength with great flexibility as it has many joints close together.
