The Small Intestine Meridian of Hand - Taiyang starts from the ulnar side of the tip of the little finger ( Shaoze, Si 1 ) ( 1 ) . Following the ulnar side of the dorsum of the hand it reaches the wrist where it emerges from the styloid process of the ulna ( 2 ) . From there it ascends along the posterior aspect of the forearm ( 3 ) , passes between the olecranon of the ulna and the medial epicondyle of the humerus, and runs along the posterior border of the lateral aspect of the upper arm ( 4 ) to the shoulder joint ( 5 ) . Circling around the scapular region ( 6 ) , it meets Dazhui ( Du 14 ) on the superior aspect of the shoulder ( 7 ) .
