Abdominal Wall

The abdominal wall is composed of muscles and tissues that form a layer that covers the front and sides of your abdomen.

The abdomen, unlike the thorax, which is the part of your chest between your neck and abdomen and pelvis, which is the part of your body between your abdomen and thighs, has no bony reinforcements or protection. The wall consists entirely of four muscle pairs, arranged in layers, and the fascia,or connective tissue that envelops them.
