The visual demonstrates a breach in the annulus fibrosus (the tough outer layer of the intervertebral disc), allowing the soft, jelly-like nucleus pulposus to protrude. This protrusion is shown making direct contact with a spinal nerve root, represented by the inflamed, red area on the nerve.

Educational: "A detailed look at spinal pathology: This model illustrates a herniated disc where the internal nucleus pulposus escapes its outer ring, causing mechanical compression and chemical irritation of the adjacent nerve root."
Clinical Focus: "Understanding Radiculopathy: When a disc herniates, it doesn't just 'slip.' It can actively compress spinal nerves, leading to the inflammation, pain, and numbness often associated with sciatica."
Patient-Friendly: "Ever wonder what 'pinched nerve' actually looks like? This visual shows how a herniated disc can press against a nerve, which is a common culprit behind chronic back and leg pain."
