25. The brachioradialis (p. 173, and Fig. 75, _k_). Reflect it carefully
to its origin and insertion.
26. The biceps (Fig. 77, _g_, and p. 165). The capsule of the
shoulder-joint may be opened in order to expose its origin. Its
insertion cannot be seen at this stage.
27. The brachialis (Figs. 75 and 79, _i_, and p. 166). Work under it
near its union with the clavobrachial; cut it at that point and reflect
it.
28. Extensor carpi radialis longus (p. 173, and Fig. 75, _l_). Note the
oblique tendon on the radial side of the wrist near the insertion of the
brachioradialis. A second tendon passes beneath its distal border. This
tendon may be separated into a deep and superficial portion. The latter
may be traced proximad to its muscle, the extensor carpi radialis
longus.
29. Extensor carpi radialis brevis (p. 174). Its tendon is the deeper of
the two tendons seen when isolating the tendon of the extensor longus.
