Rhomboid minor

What muscle and function?

Serratus anterior (protraction and rotates scapula + depresses scapula)

What muscle and function

Pectoralis minor (stabilises scapula and rotates)

Trapezius (elevates, retracts and depresses scapula)

Levator scapulae (elevates the scapula)

Rhomboid minor (retracts scapula, roates)

supraspinatus

infraspinatus

Supraspinatus (abducting)c

Acromion

Coracoid process

Infraspinatus muscle

Subscapularis muscle

Teres minor muscle

Infraspinatus muscle

Teres minor muscle

Teres major muscle (adducts and medial rotation + extension of arm when arm is already flexed)

Subscapularis

Supraspinatus

Is teres major part of glenohumeral joint? Why?

No because it doesn’t actually attach to the glenohumeral joint

Stability vs Flexibility explained?

Reduced stability means increased flexibility but become more vulnerable to dislocation and thus injurty

Pectoralis muscle (adductor of arm)

Deltoid muscle (abductor)

Latissimus dorsi (extends shoulder joint and medially rotates humerus [adductor])
