Pectoralis Minor

 

Origin: Anterior 3, 4, 5 ribs near costal cartilages

 

Insertion: Coracoid process of scapula- medial border of superior surface

 

Action: Protection, depression, downward rotation of scapula

 

Nerve: Medial pectoral nerve (Cervical 8, Thoracic 1)

 

Palpate: Difficult to palpate. Position arm with the hand behind the back to relax pectoralis major. Place palpating fingertip on coracoid process and lay finger just in front of anterior border of deltoid. Palpate pectoralis minor as the hand is actively lifted away from the back during scapular protraction.

 

This muscle forms the anterior wall of the axilla.
