FLEXOR CARPI ULNARIS OriginHumeral head: common flexor origin of med epicondyle. Ulnar head: aponeurosis from med olecranon and upper three quarters subcutaneous border of ulna ActionFlexes and adducts wrist. Fixes pisiform during action of hypothenar muscles InsertionPisiform, hook of hamate, base of 5th MC via pisohamate and pisometacarpal ligs NerveUlnar N (C6, 7) (by communication from lat ..

FLEXOR CARPI RADIALIS OriginCommon flexor origin of med epicondyle of humerus ActionFlexes and abducts wrist InsertionBases of 2nd and 3rd MCs via groove in trapezium and slip to scaphoid NerveMedian N (C6, 7) (from med and lat cords)

EXTERNAL ABDOMINAL OBLIQUE OriginAnt angles of lower eight ribs ActionSupports abdominal wall, assists forced expiration, aids raising intraabdominaol pressure and, with muscles of opposite side, abducts and rotates trunk InsertionOuter ant half of iliac crest, inguinal lig, public tubercle and crest, and aponeurosis of ant rectus sheath NerveAnt primary rami(T7-12)

EXTENSOR POLLICIS LONGUS OriginMiddle third of post ulna (below abductor pollicis longus) and adjacent interosseous membrane ActionExtends IP and MCP jnts of thumb InsertionBase of distal phalanx of thumb via Lister's tubercle (dorsal tubercle of radius). NervePost interosseous N (C7 , 8 )

EXTENSOR POLLICIS BREVIS OriginLower third of post shaft of radius and adjacent interosseous membrane ActionExtends MCP jnt of thumb InsertionOver tendons of radial extensors and brachioradialis to base of prox phalanx of thumb NervePost interosseous N (C7, 8)

EXTENSOR INDICIS OriginLower post shaft of ulna (below extensor pollicis longus) and adjacent interosseous membrane ActionExtends all jnts of index finger InsertionExtensor expansion of index finger (tendon lies on ulnar side of extensor digitorum tendon) NervePost interosseous N (C7, 8)

EXTENSOR HALLUCIS LONGUS OriginMiddle half of ant shaft of fibula ActionExtends big toe and foot. Inverts foot and tightens subtalar jnts InsertionBase of distal phalanx of great toe NerveDeep peroneal N (L5, S1)

EXTENSOR DIGITORUM LONGUS OriginUpper two thirds of ant shaft of fibula, interosseous membrane and sup tibiofibular jnt ActionExtends toes and extends foot at ankle InsertionExtensor expansion of lat four toes NerveDeep peroneal N (L5, S1)

EXTENSOR DIGITORUM BREVIS OriginSup surface of ant calcaneus ActionExtends toes when foot fully dorsiflexed InsertionFour tendons into prox phalanx of big toe and long extensor tendons to toes 2, 3 and 4 NerveDeep peroneal N (L5, S1)

EXTENSOR DIGITORUM OriginCommon extensor origin on ant aspect of lat epicondyle of humerus ActionExtends all jnts of fingers InsertionExt expansion to middle and distal phalanges by four tendons. Tendons 3 and 4 usually fuse and little finger just receives a slip NervePost interosseous N (C7, 8)
