Study Notes
Muscles of the Glenohumeral Joint (GH Joint)
- The latissimus dorsi is responsible for adduction, medial rotation, and extension of the GH joint.
- The supraspinatus initiates GH abduction and is part of the rotator cuff.
- The infraspinatus is responsible for lateral rotation of the GH joint and is part of the rotator cuff.
- The serratus anterior facilitates scapula protraction, depression, and medial rotation.
- The subscapularis keeps the scapula against the thoracic wall.
- The trapezius is responsible for scapula elevation, lateral rotation, retraction, and depression.
- The rhomboid major and rhomboid minor are responsible for scapula retraction and elevation.
- The teres minor is responsible for lateral rotation of the GH joint and is part of the rotator cuff.
- The pectoralis major is responsible for medial rotation of the GH joint.
- The pectoralis minor aids in scapula protraction, depression, and medial rotation.
- The serratus anterior also assists with scapula protraction, lateral rotation, and stabilizing the scapula against the thoracic wall.
- The trapezius contributes to scapula elevation as well.
