Which point is directly below the outer canthus, in the depression at the lower border of the zygomatic bone?

• A. SI 17
• B. SI 16
• C. SI 18
• D. SI 15

Answer: (A)

The point being tested is identified by its exact facial position: directly below the outer corner of the eye, in the depression at the lower edge of the cheekbone (zygomatic bone). That anatomical spot corresponds to Small Intestine channel point located in the infraorbital region, often used for issues around the eye and cheek area. Among the options, this precise infraorbital depression is what marks that specific point on the SI channel, making it the correct choice. The other points lie in different regions on the face or neck and do not occupy this infraorbital location.
