Which point is at the root of the neck, superior to the medial end of the clavicle, directly below Renying ST-9 in the depression between the sternal and clavicular heads of the sternocleidomastoid?

• A. ST 11
• B. ST 10
• C. ST 9
• D. ST 12

Answer: (A)

The key idea is exact neck geography for the stomach channel points. ST-11 sits at the root of the neck in the hollow formed by the two heads of the sternocleidomastoid, just above the medial end of the clavicle, and directly below Renying (ST-9). That precise position—root of the neck, in the SCM depression between its sternal and clavicular heads, and just above the clavicle—is what the description calls for. The other points lie in different neck or chest locations, not in this specific depression at the root of the neck, which is why ST-11 is the correct choice.
