M. abductor pollicis longus ( fig. 11 )

ORIGIN: A lateral head from the dorsal surface of the head of the radius, and a medial head from a fossa formed by the posterior crest of the olecranon process of the ulna.

INSERTION: Via a tendon on the medial surface of the first metacarpal, just deep to the os falciforme.

REMARKS: This muscle has the same general form in the 11 study taxa. In Condylura , the tendon of insertion continues past the first metacarpal to attach to the medial surface of the ungual phalanx, and in Uropsilus , the origin of the medial head extends well down on the shaft of the radius.
