Cartilaginous joints are found between bones of the spine. A cutaway view of the spine shows that the vertebrae encircling the spinal cord are covered with the clear, glassy connective tissue know as hyaline cartilage. In between the vertebrae are the spinal disks-pads of a tougher, fiber-filled material called fibrocartilage. These disks allow the spine, which would otherwise be inflexible to articulate freely in various directions. Able to withstand compression, the cartilage disks act as shock absorbers, cushioning the spine from injury.
