23. The quadriceps femoris (p. 201). Isolate the rectus femoris (Fig.
92, _b_) as far as its junction with the vastus lateralis; cut it at
this point and reflect its proximal portion. Turn aside the distal end
and find beneath it the transverse aponeurosis between the vastus
medialis and the vastus lateralis, and covering the vastus intermedius.
The vastus lateralis (Fig. 90, _d_) may be cut near the middle and
dissected up from its origin in both directions; the vastus intermedius
is thus exposed. The vastus medialis (Fig. 92, _c_) and the vastus
intermedius need not be cut.
24. The gastrocnemius (p. 203, and Fig. 90, _m_; Fig. 91, _k_). It may
be raised cautiously near its middle and divided. Care should be taken
not to divide the underlying plantaris (Fig. 90, _l_). After noting the
connection of the outer head with the plantaris, the latter may be
divided and reflected, together with the outer head.
