The vertebral column (spine or backbone) is a curved structure composed of bony vertebrae that are interconnected by cartilaginous intervertebral discs. It is part of the axial skeleton and extends from the base of the skull to the tip of the coccyx. The spinal cord runs through its center. The vertebral column is divided into five regions and consists of 33 vertebrae interlaced by strong joints and ligaments. Although the spine can be a pain in the back,(no pun intended) its function is very im

The vertebral column is a multi-articular, segmented structure that is typically made of up 33 vertebrae along with many ligaments, muscles and intervertebral discs. The structures that form the vertebral column must be rigid enough to support the trunk and the limbs, strong enough to protect the spinal cord and anchor the deep spinal muscles, and yet sufficiently flexible to allow for movement of the head and trunk in multiple directions. The curves of the spine make the structure particularly
