1 Bones, Actions/Movements, and Muscles REVIEW OF THE WRISTBones, Actions/Movements, and Muscles
2 Extensor Indicis Dorsal Origin: Insertion: Actions: Distal, posterior ulnaInsertion:middle and distal phalanxes of the second phalangeActions:Extension of the 2nd fingerWeak wrist extension
3 Lunate213TrapeziumTrapezoid42nd Metacarpal5Proximal Phalanx of the 4th Phalange
4 Flexor Digitorum Superficialis PalmarOrigin: medial condyle of the humerusulnar head - medial coronoid arearadial head - radial tuberosity areaInsertion: split tendons attach to the sides of the middle phalanx of the four fingers (palmar surface)Actions:flexion of elbow, wrist and fingers
5 What muscle inserts on palmar surface at the base of the 5th metacarpal and the pisiform? Flexor carpi ulnaris
6 Name the action at the wrist FlexionUlnar flexion or adduction
7 Palmaris Palmar Origin: Medial epicondyle Insertion: Palmar aponeurosisAction: flexion of the wrist
8 What nerve passes through the carpal tunnel? Median nerve
17 Extensor Digitorum Dorsal origin: lateral condyle of the humerus insertion: middle and distal phalanges of the four fingers (dorsal side)action: extension of the elbow, wrist and fingers
18 Name the action at the fingers FlexionAdbuction
19 What muscle inserts on the dorsal surface at the base of the 5th metacarpal? Extensor carpi ulnarisEXTENSOR because it is on the dorsal surface.CARPI because it inserts on a metacarpal (or carpal) boneULNAR because it inserts to the medial side (5th metacarpal) of the wrist.
20 Flexor Carpi Ulnaris ? Palmar Origin: medial condyle of the humerus Insertion: pisiform, base of the 5th metacarpalAction:flexion of the elbowflexion of the wristadduction of the wrist?
21 Action at her wrists?FlexionAction at his wrists?Adduction
23 Flexor Carpi Radialis ? Palmar Origin: medial condyle of the humerus Insertion: base of the 2nd and 3rd metacapals (palmar surface)Action:flexion of the elbowflexion of the wristabduction of the wrist?
25 Extensor Pollicis Longus Dorsalorigin: upper posterior surface of the ulnainsertion: base of the last phalanx of the thumb (dorsal side)action: extension of the wrist and thumbpalpation: most prominent on the dorsal side of the hand
