Document Summary

The deltoideus muscle is a superficial muscle of the lateral scapular area with the following attachments: scapular spine and acromion; to: deltoid tuberosity of humerus; it spans the caudal aspect (flexor surface) of the shoulder joint. Cephalic = head; brachium=arm brachiocephalicus = head to brachium. The omotransversarius muscle has the following attachments: distal scapular spine; to: wing of atlas; its caudal aspect is superficial, and its cranial aspect runs deep to the brachiocephalicus muscle. The trapezius is a superficial muscle over the dorsal scapular area and has the following attachments: median raphe of neck from c3-c7 and supraspinous ligament from t1 to t9; to: scapular spine. The lateral head of the triceps muscle is one of the 4 heads of the triceps with the following attachments: proximolateral humerus (tricipital line); to: The lateral head of the triceps forms the lateral aspect of the brachium and spans the caudal (extensor) surface of the elbow joint.
