28. The popliteus (p. 206, and Fig. 92, _k_). Cut very near the origin
and reflect.
The three following deep muscles on the ventral surface of the shank are
covered by the deep crural fascia (p. 206) which separates them from the
overlying muscles. It should be removed.
29. The flexor longus hallucis (p. 207, and Fig. 91, _m_). Divide the
muscle at its junction with the tendon. Open the canals on the
astragalus and calcaneus and reflect the tendon, cutting the tendon of
the flexor longus digitorum near its insertion and dividing at the
middle the quadratus plantæ (p. 213) which may be found inserted into
its ventral surface.
30. Flexor longus digitorum (p. 208, and Fig. 91, _n_). This may be
divided very near its origin.
31. Tibialis posterior (p. 208, and Fig. 91, _o_). This may be divided
near its tendon.
32. Peroneus longus (p. 209, and Fig. 90, _q_). The overlying tendons
may be cut in tracing its insertion.
