38. Palmaris longus (p. 179, and Fig. 77, _s_). In dissecting this
muscle be careful not to injure the part of the flexor sublimis (Fig.
77, _x_) that rises from its surface (see flexor sublimis, p. 181). Cut
the palmaris proximad of the origin of the flexor sublimis and reflect
it.
39. Flexor sublimis digitorum (p. 181 and Fig. 77, _x_). Trace one or
two of the tendons through the sheaths on the ventral surfaces of the
first phalanges. Cut and reflect the radial portion.
40. Flexor profundus digitorum (p. 181, and Fig. 77, _u_). After
recognizing the parts cut through the tendons of the first and fifth
parts and reflect them to determine their origin. Then cut through the
common tendon so as to reflect the other three parts together. Trace one
or two of the tendons to the distal end of the digit.
