Which point is directly anterior to the angle of the jaw, in a depression at the anterior border of the masseter muscle?

• A. St 6
• B. St 5
• C. St 7
• D. St 9

Answer: (B)

Stomach 5 sits in a shallow hollow directly in front of the angle of the mandible, at the anterior border of the masseter muscle. This exact location—an indentation just anterior to where the masseter runs along the jawline—defines the point on the Stomach channel used for facial and jaw issues. Clinically it’s chosen for problems like jaw stiffness, toothache, facial swelling, and facial nerve palsy because it lies right where the masseter and facial structures align along the jaw. The other nearby facial points are located at different landmarks around the jaw or ear, not in this particular hollow in front of the masseter, so they don’t share this specific anatomical relationship.
