The Small Intestine meridian follows a course that begins at the end of the little finger and ends at the abdomen, with two branches.
The Sun Small Intestine meridian of the hand begins at the end of the little finger and continues along the lateral side of the palm, reaches the wrist joint, passes through the ulnar styloid process, and follows the ulna upward, passing through the depression between the medial epicondyle of the humerus and the ulnar humerus, and then continues on upward.
It then follows the posterior external direction of the great arm to reach the shoulder joint portion of the body, where it intersects and follows the scapula, and where it meets the rest of the meridians at the shoulder joint, from where it enters the defective pelvis and connects with the heart. Along the course of the esophagus it passes from the diaphragm and finally reaches the stomach, where it belongs to the small intestine.
One of these branches, at the supraclavicular fossa branches up the neck, passes through the cheeks, travels to the outer corner of the eye and then folds outward, finally entering the ear. The other branch begins at the cheeks, passes through the nose, and then travels to the inner corners of the eyes, where it connects with the zygomatic bone.
