Which CV point is on the midline of the sternum, in a depression level with the junction of the fourth intercostal space and the sternum?

• A. CV 16
• B. CV 17
• C. CV 18
• D. CV 19

Answer: (B)

The key idea is the chest’s midline point at the level of the fourth intercostal space. At the center of the sternum, in the hollow there, the point sits exactly where the fourth intercostal space meets the sternum—that is Shanzhong, also known as CV17. This spot is the primary midline chest point, and its location aligns with the 4th intercostal space, making it distinct from other midline sternum points that sit higher or lower. So, the described depression on the midline chest at the level of the junction of the fourth intercostal space and the sternum corresponds to CV17.
