The vertebrae within the lumbar spine are separated by intervertebral joints which are unique articular structures, The intervertebral discs are the joint's key component, made up of distinct features. The nucleus shifts causing annular rings to bulge outward. Intervertebral discs are made of fibrocartilage and thereby structurally form a symphysis type of cartilaginous joint. Herniated disks (also called bulging, slipped or ruptured disks) can be painful. These vertebrae are identified by the region . Isolated notochordal remnants may escape their lineage-specific destination in the nucleus pulposus and instead attach to the outer surfaces of the vertebral bodies, from which notochordal cells largely regress.

In the intervertebral discs of young healthy adults, the typical nucleus pulposus consists of a semi-fluid mass of mucoprotein ground substance, occupying approximately 40% of the disc's cross-sectional area. Within the lumbar region, the vertebral bodies are larger than in the thoracic and cervical regions due to the lumbar spine being designed for weight-bearing purposes. Vacuum disc phenomenon is seen frequently with degenerative disc disease and is characterized by the collection of gas in the disc space.
