It helps carry sensory signals (feeling) and motor signals (movement control) between the spinal cord and the body. It is most often discussed when clinicians localize pain, numbness, or weakness patterns in the groin and upper thigh region. It is also a common anatomic target or reference point in spine imaging, injections, and surgical planning."}
