    origin:The lateral supracondylar crest.
  2. extensor carpi radialis insertion
    insertion:The small tuberosities on the dorsal surfaces of the base of metacarpals II and III.
  3. extensor carpi radialis action
    action:To extend the carpus
  4. brachioradialis origin
    origin:crest of the lateral epicondyle
  5. brachioradialis insertion
    insertion:the fascia on the craniomedial aspect of the antebrachium
  6. brachioradialis action
    action:rotate the radius craniolaterally (supination)
  7. common digital extensor origin
    origin:The lateral epicondyle of the humerus
  8. common digital extensor insertion
    insertion:The ungunal crest (extensor processes) of the distal phalanges of digits II, III, IV, and V
  9. common digital extensor action
    action:To extend the joints of the four principal digits and the carpus
  10. lateral digital extensor origin
    origin:The lateral epicondyle of the humerus
  11. lateral digital extensor insertion
    insertion:The proximal ends of all the phalanges of digits III, IV, and V, but mainly the ungunal crest (extensor processes) of the distal phalanges of these digits.
  12. lateral digital extensor action
    action:To extend the carpus and joints of digits III, IV, and V
  13. ulnaris lateralis origin
    origin:The lateral epicondyle of the humerus
  14. ulnaris lateralis insertion
    • insertion:The lateral aspect of the proximal end of metacarpal V and the accessory carpal bone. 
  15. ulnaris lateralis action
    action:To abduct the manus and flex the carpal joint and support the carpus when extended to support weight
  16. supinator origin
    origin:The lateral epicondyle of the humerus.
  17. supinator insertion
    insertion:The cranial surface of the proximal fourth of the radius
  18. supinator action
    action:To rotate the forearm laterally so that the palmar side of the paw faces medially (supination); to flex the elbow
  19. abductor pollicis (digiti I) longus origin
    origin:The lateral border and cranial surface of the body of the ulna; the interosseous membrane
  20. abductor pollicis (digiti I) longus insertion
    insertion:The proximal end of metacarpal I
  21. abductor pollicis (digiti I) longus action
    action:To abduct the first digit or pollex and extend the carpal joints
  22. pronator teres origin
    origin:The medial epicondyle of the humerus
  23. pronator teres insertion
    insertion:The medial border of the radius between the proximal and middle thirds
  24. pronator teres action
    action:To rotate the forearm medially so that the palmar side of the paw faces the ground (pronation); to flex the elbow
