SUMMARY
1. The flexor surface of the carpus is deeply concave and is converted into a tunnel by the flexor retinaculum.
2. The 4 tendons of the FDP lie deep, whereas the 4 tendons of the FDS lie superficial. These share a common synovial sheath.
3. The tendon of the FPL lies within its own synovial sheath.
4. The tendon of the FCR lies within its own fibro-osseous tunnel.
5. The median nerve passes beneath the flexor retinaculum b/w the FDS tendon (medial to n.) and FCR tendon (lateral to n.).
