Herniated Disc Anatomy: Visual Guide to Spinal Nerve Compression #3514738 (License: Personal Use)

This anatomical illustration depicts a lumbar vertebral segment where the intervertebral disc has ruptured, allowing the gel-like nucleus pulposus to extrude posteriorly and impinge on the exiting spinal nerve root. The surrounding vertebrae show spongy cancellous bone structure, while the annulus fibrosus is partially torn, highlighting the mechanism of radiculopathy. The inflamed red area indicates localized irritation and potential pain signaling.
