Which point is the master point for the chest and cranial abdomen?

The correct choice is the point that serves as the master point for the chest and cranial abdomen, which is PC-6. This point, also known as Neiguan, is significant in Traditional Chinese Veterinary Medicine (TCVM) for its ability to influence the function of the heart, pericardium, and the entire chest area.

PC-6 is positioned on the anterior aspect of the forelimb and is particularly known for its role in alleviating nausea, regulating the heart, and improving circulation to the areas above the diaphragm. Its capability to affect the thoracic and abdominal organs makes it a powerful point for treating conditions related to the chest and upper digestive system, thus the reason why it is termed the master point for these areas.

The other options do not specifically serve as the master point for the chest and cranial abdomen. CV-12 is associated with digestive issues but is not referred to as a master point for the chest. SI-9 is primarily linked with shoulder conditions and does not cover the chest area extensively. LIV-13 is often considered for spleen and stomach health but is not focused specifically on the chest region in the same way PC-6 is.
