Posterior abdominal wall

Paries abdominalis posterior · Zadní břišní stěna

Skeleton

Looks like

The back wall of the belly: lumbar spine, the lower ribs, the psoas and quadratus muscles and the diaphragm's lower part.

What it does

Supports the kidneys, aorta and large veins that lie against it and anchors the hip-bending muscles.

Keeping it well

Pain from kidneys, pancreas or an aortic aneurysm can be felt here as back pain; sudden severe pain with collapse is an emergency.
