General
Appearances of the Abdominal Wall
The normal abdominal wall is soft and pliable and undergoes inward
and outward excursion with respiration. The contour is subject to considerable
variation and depends on the tone of its muscles and the amount of fat in the
subcutaneous tissue. Well-developed muscles or an abundance of fat can prove to
be a severe obstacle to the palpation of the abdominal viscera
.

Infection of the Umbilicus
In the adult, the umbilicus often receives scant attention
in the shower and is consequently a common site of infection.
Surgical
Incisions
If possible, all surgical incisions should be made in the
lines of cleavage where the bundles of collagen fibers in the dermis run in
parallel rows. An incision along a cleavage line will heal as a narrow scar,
whereas one that crosses the lines will heal as wide or heaped-up scars.
