Posterior thoracic wall
Paries thoracis posterior · Zadní hrudní stěna
Skeleton
Looks like
The back of the chest: the thoracic spine and the back parts of the ribs, with the deep back muscles over them.
What it does
Supports the trunk, protects the spinal cord and the back of the lungs and anchors the ribs.
Keeping it well
Back pain between the shoulder blades is usually muscular; sudden tearing pain there can be an aortic problem — an emergency.
