Which point is in the depression between the angle of the mandible and the anterior border of the sternocleidomastoid muscle?

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

Answer: (A)

The point being tested is the precise neck landmark of the Small Intestine channel. The description describes a depression located between the angle of the mandible (the jaw corner) and the anterior border of the sternocleidomastoid muscle. That exact anatomical spot corresponds to SI-16. Recognizing how the neck landmarks map to the SI channel helps you identify this point: SI-16 sits in that neck depression, making it the best match for this description.

The other options lie in different locations around the neck or face, not in this specific depression, so they don’t fit the described landmark. This is why the described depression points to the SI-16 location.
