Nervous / VISUAL EXPLAINER
Why Can Carpal Tunnel Syndrome Make Fingers Tingle?
Pressure on the median nerve within the wrist tunnel can disturb sensation. Swollen tissue around the flexor tendons can reduce space for the nerve. Tingling has other causes, so this is not a diagnostic map.

What the illustration shows
English educational poster titled Why Can Carpal Tunnel Syndrome Make Fingers Tingle? A large oblique wrist cutaway shows a gold median nerve beneath a continuous translucent ligament roof, above smooth ivory selected flexor tendons within a U-shaped carpal bony arch. Peach surrounding synovial tissue is labeled as swollen. White leaders identify roof, median nerve, surrounding tissue, tendons and carpal bones. Lower panels compare more room with crowding; the gold nerve is flatter in the crowding view. A neutral palm-facing hand has a small wrist location box without colored finger territories. Text explains that swelling can reduce available space and press on the nerve. The visible note says selected structures, transparent roof, not to scale, and hand tingling has other causes; this is not a diagnostic map. Gold AllHumanBody.com and the exact project slogan sit on plain navy.
How to interpret this poster
- Selected structures, not nine-tendon inventory, surgical map or measured compression. Transparent roof is not division; comparison is not treatment before/after.
- AI-assisted educational illustration; not physician certification, a diagnosis or individualized medical advice.
- Fine annotations require enlargement; preserve the full uncropped illustration and its qualifiers.
