Mechanical low back pain can originate from several tissue types that have nociceptors and can transmit pain. The broad pain generators include the vertebrae, facet joints, intervertebral discs, the muscles of the back, the fascia surrounding these tissues, the ligaments that stabilize the spine, and the nerves (nerve roots and peripheral nerves) that can become irritated or compressed. A comprehensive understanding must include all of these structures because each can contribute to pain in mechanical back pain. The option that lists vertebrae, facets, discs, muscles, fascia, ligaments, and nerves is the best because it captures all the possible sources. Other lists omit one or more of these components (for example, missing fascia/ligaments or missing nerves), so they don’t reflect every potential generator of mechanical back pain.
