Division of muscle connection
Muscles of the shoulder joint and shoulder girdle: this is any which connect between the axial skeleton, shoulder girdle (scapula + clavicle?), and humerus.

- Axial skeleton and shoulder girdle (scapula mostly but clavicle too)
- Trapezius
- Levator scapulae
- Pectoralis minor
- Rhomboid minor
- Rhomboid major
- Serratus anterior
- Between scapula humerus and clavicle
- rotator cuff muscles
- supraspinatus
- teres minor
- subscapularis
- Teres major
- Deltoid
- between axial skeleton and humerus
- Pectoralis major
