Answer: A The pectoralis minor muscle attaches to the coracoid process of the scapula and ribs 3, 4, and 5. When the pectoralis minor is contracted, it causes an anterior rotation of the scapula, which creates a forward roll in the shoulder. Another primary muscle which contributes to the forward rolled shoulder syndrome is the pectoralis major which attaches to the clavicle, ribs, and humerus.
