Types of herniated intervertebral discs. Artwork of an axial view of a slipped (herniated) disc in the lumbar (lower back) spine. Herniation of the fibrocartilage disc (green) between each vertebra (light brown) is where the disc's pulpy interior (nucleus pulposus, dark green) protrudes through the damaged outer ring (annulus fibrosus, light green). This extruded material can press on the nerve roots (left and right, yellow) and spinal nerves (at this level, the cauda equina). The four types of herniation shown are: central, posterolateral, foramenal, and far lateral. Spinal disc herniation can cause pain and in severe cases may require surgery.
