  1. Extensor carpi radialis
    • Origin- The lateral supracondylar crast.
    • Insertion- The small tuberosities on the dorsal surfaces of the base of metacarpals II and III.
    • Action- To extend the carpus.
    • Innervation- Radial nerve.
  2. Common digital extensor
    • Origin- The lateral epicondyle (humerus).
    • Insertion- The extensor processes of the distal phalanges of digits II-V.
    • Action- To extend the Joints of the 4 principal digits and the carpus.
    • Innervation- Radial nerve.
  3. Lateral digital extensor
    • Origin- The lateral epicondyle (humerus).
    • Insertion- The proximal ends of all phalanges of digits III-V, but mainly the extensor processes of the distal phalanges of the digits.
    • Action- To extend the carpus and joints of digits III-V.
    • Innervation- Radial nerve.
  4. Ulnaris lateralis
    • Origin- The lateral epicondyle (humerus).
    • Insertion- The lateral aspect of the proximal end of metacarpal V and the accessory carpal bone.
    • Action- To abduct the carpal joint; to support the carpus when extended to support weight.
    • Innervation- Radial nerve.
  5. Supinator
    • Origin- The lateral epicondyle (humerus).
    • Insertion- The cranial surface of the proximal fourth of the radius.
    • Action- Supination; to flex the elbow.
    • Innervation- Radial nerve.
  6. Abductor digitii I longus
    • Origin- The lateral border and cranial surface of the body of the ulna; the interosseous membrane.
    • Insertion- The proximal end of metacarpal I.
    • Action- To abuct the first digit or pollex and extend the carpal joints.
    • Innervation- Radial nerve.
