This exhibit depicts the superior anatomy of a cervical vertebra with a posterolateral disc bulge. Intervertebral discs are situated between each vertebral body of the spinal column. They serve as cushions to absorb shock and give the spine flexibility. A normal intervertebral disc consists of a tough outer annulus and a soft inner nucleus. If the annulus is weakened, the nucleus can begin to push through the inner annular fibers, causing the disc to bulge into the spinal canal and neural foramina. This can be asymptomatic, or lead to symptoms including radicular pain and numbness.
