Paries thoracis lateralis dexter · Pravá boční hrudní stěna
Muscles
Looks like
The side of the chest under the armpit, made of ribs covered by the serratus anterior and the edges of the chest and back muscles.
What it does
Protects the lungs and moves with breathing; shelters the nerves and vessels running to the arm and breast.
Keeping it well
Pain here is often muscular; a new lump in the armpit or sharp pain with breathlessness needs a doctor.
