The af has a hierarchical lamellar structure of layered, dense bundles of aligned type i collagen, in which fibre orientation alternates in adjacent lamellae. Each intervertebral joint is a complex of three separate joints;
Which Structure Contacts The Intervertebral Disc. In the anterior annulus fibrosus, the thickness of lamellae increases abruptly 2 mm inward from the edge of the disc, dividing the annulus into peripheral and transitional regions. These structural and biomechanical changes are related to degenerative changes that occur in association with aging and trauma. The intervertebral disc is composed of a complex tissue that separates neighboring vertebrae, permits a wide range of motion, and cushions the high biomechanical forces on the spine.

The spine can be considered a column of relatively rigid vertebrae connected by flexible intervertebral discs. The discs act as shock absorbers to the loads placed on the spine and allow movement of the spine. The discs allow some vertebral motion: Intervertebral discs are pads of fibrocartilage located between the 33 vertebrae in humans and serve a set of functions, including protecting the vertebrae and nerves in the spine.
The vertebral arch and processes have thicker coverings of cortical bone.
If the discs can’t perform their roles, the health of the vertebrae are affected, and this impacts the spine as a whole. Combined, they make up one fourth the height of the spinal column. Anatomy of the intervertebral discs. Disc degeneration leads to a loss of function and is often associated with excruciating pain.
