| deep part of flexor retinaculum | <anatomy> A strong fibrous band crossing the front of the carpus and binding down the flexor tendons of the digits and the flexor carpi radialis tendon and the median nerve; in so doing it creates the carpal tunnel. Synonym: retinaculum flexorum, deep part of flexor retinaculum, flexor retinaculum, ligamentum carpi transversum, ligamentum carpi volare, volar carpal ligament. (05 Mar 2000) |

| tendon sheath of flexor digitorum longus muscle of foot | The synovial sheath that envelops the flexor digitorum longus tendons as they pass into the foot deep to the flexor retinaculum. Synonym: vagina tendinum musculi flexoris digitorum pedis longi. (05 Mar 2000) |
| tendon sheath of flexor hallucis longus muscle | <anatomy> The synovial sheath that envelops the tendon of the flexor hallucis longus as it passes into the foot deep to the flexor retinaculum. Synonym: vagina tendinis musculi flexoris hallucis longi. (05 Mar 2000) |
| tendon sheath of flexor pollicis longus muscle | <anatomy> The synovial sheath that envelops the tendon of the flexor pollicis longus in its course through the carpal canal; it is continuous with the digital sheath of the thumb, the two generally being considered as one sheath.
