| Definitions |
This currently groups the major and minor muscles (which have different attachment sites) as well as the AAO structure: Muscle which is comprised of three heads. The anterior head is the portio epicoracoidea that originates on the epicoracoid cartilage and inserts on the deltoid crest of the humerus. The next more posterior head, portio sternalis, originates on the sternum and inserts in the groove next to the deltoid crest of the humerus. The most posterior head, portio abdominalis, arises from the M. rectus abdominis and inserts on the deltoid crest of the humerus Muscles of the upper chest. The term may refer to one of two muscles, the pectoralis major and pectoralis minor. The former is a thick muscle in the anterior portion of the chest. Its action involves flexion, medial rotation, and adduction of the humerus. The latter is a thin muscle located beneath the pectoralis major. Its action involves lowering the scapula and raising the ribs. |
