Document Summary
Movements: arm flexion (shoulder) , forearm flexion (elbow), forearm supination. Long head supraglenoid tubercle to bicipital aponeurosis. Short head coracoid process to bicipital aponeurosis. These muscles are located just underneath the superficial layer. Attachments: coracoid process to ant. middle 1/3 of humerus. Attachments: distal 1/3 of ant. humerus to coronoid process and ulnar tuberosity. Long head infraglenoid tubercle to olecranon process. Lateral head upper of post. humerus to olecranon process. Medial head lower 2/3 of medial and post. humerus to olecranon process. This artery starts as subclavian (grey) then turns to axillary (blue) with its several branches and finishes as the brachial artery (red). ** there are 3 anatomoses in the arm. Anatomoses: two vessels come together and provides an alternative route for blood flow to get to a certain area. Arteries in the arm tends to get crushed with movement, this allows and alternative route so blood can still pass through.
