Chest wall anatomy | PHYSIO-graphy

The skeletal framework of the thoracic wall consists of the sternum (anteriorly), twelve ribs (laterally), and twelve thoracic vertebrae (posteriorly). It provides a rich amount of attachment sites for muscles of the neck, abdomen, back, and upper limbs. Some of these muscles attached to the ribs function as accessory respiratory muscles. www.anatomy.app | Anatomy.app
