(c) The medial head ([Fig. 79], g, h, and j).

24. The anconeus ([p. 170], and [Fig. 80], l).

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.

30. Extensor communis digitorum ([p. 174], and [Fig. 75], m).

31. Extensor lateralis digitorum ([p. 175], and [Fig. 75], n).

32. Extensor carpi ulnaris ([p. 176], and [Fig. 75], o).
