Lumbar Vertebra (L4 & L5) Compressed Status - White background

Image Description:

The illustrations depicts the lumbar spine at L4 & L5 under compression on a white background.

Further anatomy detail includes the interspinal muscle. There are paired muscles located between the spinous processes of adjacent vertebrae; subdivided into cervical, thoracic, and lumbar muscles. The interspinal muscles are short bands of muscle fibres including the interspinales cervicis, interspinales thoracis, and interspinales lumborum muscles.

Protected by the vertebrae, the spinal cord splits out between the vertebrae L1 and L2. The nervous tissue that extends below this point are individual strands that collectively form the cauda equina. In between each lumbar vertebra a nerve root exits, coming together again to form the largest single nerve in the human body, the sciatic nerve. Any disorders of the back may be of a result of this sciatic nerve having become trapped through spinal disc herniation that can affect the nerve root. Pain manifests itself as lower back pain, that radiates along the sciatic nerve through the back of the leg and down to the foot.
