14 Muscles of the thoracic wall The M. pectoralis major shapes the surface of the anterior upper thoracic wall. Beneath this muscle lies the M. pectoralis minor. These two muscles, together with the M. subclavius, belong to the group of ventral muscles of the shoulder girdle (Tab. 26). The Mm. intercostales externi and interni fill the intercostal spaces. The Mm. subcostales and the M. transversus thoracis…
