Gluteus maximus muscle. (See Fig. 243.)

Clean and study the muscle. Then separate its border and cut it
transversely at its origin, and as you turn it down notice the structures
beneath and the inferior gluteal nerve passing into the muscle. Cut this
nerve and turn the muscle dowTi to its insertion.

Gluteus medius muscle is now exposed. (See Fig. 246.)

Study this muscle. Cut it vat its origin and turn it down to its inser-
tion with care so as not to destroy the structures beneath.

turn the skin off.

In removing the skin from the anterior part of the leg care must be
used not to destroy the musculo-cutaneous, internal or long saphenous,
and external saphenous nerves. (See Fig. 242.)
