The Large Intestine Meridian continues along the radial side of the upper arm, between the anterior and mid-section of the deltoid muscle to the shoulder.

From there it flows behind the clavicle, over the shoulder (LI16) and up the lateral neck region. First running to the posterior border of the sternocleidomastoid muscle, then between its two muscle bulges and a small depression in front of the angle of the jaw. Going next to the cheek and on to the corner of the mouth.

Under the nose the Large Intestine Meridians cross each other in the point GV26, ending next to the nostril of the opposite side of the body in point LI20.

From LI15 the Large Intestine Meridian runs in its inner pathway, over SI12 to the 7th cervical vertebra (GV14), then to ST12.
