Instability: unparallel amongst major body regions, facilitate this motion is the reason. Geometric complex: bone shapes, kinematic redundancy (closed linked) Experimental inaccessibility: try getting subscap emg. Bones, joints (labrum, ligaments), muscles, bursa, nerves, vasculature. Inside-out approach: (bold is shoulder) (cid:1) (cid:1) (cid:1) (cid:1) (cid:1) (cid:1: sternum sternoclavicular clavicle . Acromioclavicular scapula (to ribs scapulothoracic) glenohumeral humerus elbow (simplified) forearm wrist (simplified) hand . Strength - force transmission (movements, joint contact forces) Breastbone and is the base of the arm. Attached to ribs by cartilage and has several palpable points: suprasternal notch (jugular notch) and xiphoid process. Relatively low inherent stability (from joint shape) Ligaments actively routinely provide joint stabilization + limb rom of clavicle.
