The extensor carpiulnaris arises from the posterior part of the external condyleof the humerus, and is inserted, like the preceding, into the ospisiforme, whence it is prolonged beneath the carpus, so as toperform the office of a flexor of the wrist.

The ( extensor proprius minimi digiti is represented by twomuscles: one of these, called the 6 extensor of the pastern, fig.

The secondmuscle, placed between the above and the preceding muscle,furnishes a similar tendon, which, after passing in front of thecarpus, becomes united at an acute angle with that of the former,the two co-operating with each other in extending the foot. Thetendon of the abductor longus pollicis is implanted into theinternal surface of the base of the metacarpal, so that it thusbecomes an extensor of the foot: it is the £ oblique extensor ofthe cannon in Hippotomy.
