Which of the following is an example of an extraordinary point in TCVM?

In Traditional Chinese Veterinary Medicine (TCVM), extraordinary points are distinct from the traditional meridian points and are often used for specific therapeutic needs. Baihui, also known as GV20, is classified as an extraordinary point because it plays a significant role in many TCVM treatments. It is located at the vertex of the skull, where it serves as a convergence point for several channels, making it integral in addressing issues related to the head and neurological functions.

Baihui is particularly important for its influence on the conveyance of Qi throughout the body and its connection to the mind, making it valuable for conditions such as seizures, behavioral problems, or head-related ailments. The other options listed, while important acupuncture points, fall under traditional meridian points rather than extraordinary points. This classification is crucial for practitioners to understand as it shapes their approach in diagnosing and treating various conditions in veterinary practice.
