Anatomical landmarks include fixed landmarks and moving landmarks.
Fixed anatomical landmarks are those that would not change with body movement and visible or palpable on the body surface. They include the five sensory organs, hair, nails, nipple, umbilicus, and prominence and depression of the bones as well as texture of the muscles. With the aid of these landmarks, acupoints can be located directly. Examples are Suliao (CV 25) on the tip of the nose, Yuyao (EX-HN4) on the central point of the eyebrows and Shenque (CV 8) on the umbilicus.
Moving landmarks refer to those that will appear only when a part of the body keeps in a specific position. Such anatomical landmarks can be used to locate some acupoints. For instance, the prominence on the masseter in chewing is Jiache (ST 6).
