Right Cervical Disc Herniation
This exhibit depicts the superior anatomy of a cervical vertebra with a posterolateral disc herniation. 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 herniate through the annular fibers, impinging the spinal cord and nerve roots. This can be asymptomatic, or lead to symptoms including radicular pain, numbness, and paralysis.
