I - anteromedial surface of the humeral shaft
Trapezius
A - The trapezius elevates, depresses, rotates, and retracts the scapula, or shoulder blade
O - It originates on the occipital bone, the ligamentum nuchae, and the spinous processes of T01–T12
I - lateral third of the clavicle, as well as the acromion and scapular spine of the scapula
Latisimus dorsi
A -extension, adduction, transverse extension also known as horizontal abduction, flexion from an extended position, and (medial) internal rotation of the shoulder joint.
O - Origin of the latissimus dorsi is from spinous processes of thoracic T7–T12, thoracolumbar fascia, iliac crest and inferior 3 or 4 ribs, inferior angle of scapula
I - insertion on floor of intertubercular groove of the humerus.
Rhomboid Major
A -Retracts the scapula
O - T2 to T5
