| deep head of flexor pollicis brevis | The head of short flexor of the thumb that arises from the trapezoid and capitate bones and transverse carpal ligaments. It is innervated by the deep ulner nerve, and considered by many to be the first palmar interosseous muscle. Synonym: caput profundum musculi flexoris pollicis brevis. (05 Mar 2000) |
| 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 carpi radialis muscle | <anatomy> The synovial sheath enclosing the tendon of the flexor carpi radialis as it crosses the wrist. Synonym: vagina tendinis musculi flexoris carpi radialis. (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. Synonym: vagina tendinis musculi flexoris pollicis longi, radial bursa. (05 Mar 2000) |
| ulnar flexor muscle of wrist | <anatomy, muscle> Origin, humeral head from medial condyle of humerus, ulnar head from olecranon and upper three-fifths of posterior border of ulna; insertion, pisiform bone, but is continued to the fifth metacarpal bone via the pisometacarpal ligament; action, flexes and abducts wrist ulnarward; nerve supply, ulnar. Synonym: musculus flexor carpi ulnaris, ulnar flexor muscle of wrist. (05 Mar 2000) |
| flexor | <anatomy> A muscle which bends or flexes any part; as, the flexors of the arm or the hand; opposed to extensor. Source: Websters Dictionary (01 Mar 1998) |
| flexor carpi radialis | <anatomy, muscle> Origin, common flexor origin of the medial condyle of humerus; insertion, anterior surface of the base of the second and most often sending a slip to that of the third metacarpal bone; action, flexes and abducts wrist radialward; nerve supply, median; its tendon travels in its own canal roofed by a layer of the transverse carpal ligament. Synonym: musculus flexor carpi radialis, radial flexor muscle of wrist. (05 Mar 2000) |
| flexor carpi ulnaris | <anatomy, muscle> Origin, humeral head from medial condyle of humerus, ulnar head from olecranon and upper three-fifths of posterior border of ulna; insertion, pisiform bone, but is continued to the fifth metacarpal bone via the pisometacarpal ligament; action, flexes and abducts wrist ulnarward; nerve supply, ulnar. Synonym: musculus flexor carpi ulnaris, ulnar flexor muscle of wrist. (05 Mar 2000) |
| flexor digiti minimi brevis muscle of foot | Origin, base of metatarsal bone of the little toe and sheath of musculus peroneus longus; insertion, lateral surface of base of proximal phalanx of little toe; action, flexes the proximal phalanx of the little toe; nerve supply, lateral plantar. Synonym: musculus flexor digiti minimi brevis pedis, short flexor muscle of little toe. (05 Mar 2000) |
| flexor digiti minimi brevis muscle of hand | Origin, hamulus of hamate bone; insertion, medial side of proximal phalanx of little finger; action, flexes proximal phalanx of little finger; nerve supply, ulnar. Synonym: musculus flexor digiti minimi brevis manus, short flexor muscle of little finger. (05 Mar 2000) |
| flexor digitorum brevis | <anatomy, muscle> Origin, medial tubercle of calcaneus and central portion of plantar fascia; insertion, middle phalanges of four lateral toes by tendons perforated by those of the flexor longus; action, flexes lateral four toes; nerve supply, medial plantar. Synonym: musculus flexor digitorum brevis, musculus flexor brevis digitorum, short flexor muscle of toes. (05 Mar 2000) |
| flexor digitorum longus | <anatomy, muscle> Origin, middle third of posterior surface of tibia; insertion, by four tendons, perforating those of the flexor brevis, into bases of distal phalanges of four lateral toes; action, flexes second to fifth toes; nerve supply, tibial nerve.
