Where does the PC divergent channel emerge?

The PC (Pericardium) divergent channel emerges behind the ear, which is a critical point in understanding the trajectory of this channel within Traditional Chinese Medicine. Divergent channels are pathways that separate from the primary channels and serve to connect the internal organs with their respective exterior manifestations.

In the case of the PC divergent channel, after diverging from the primary channel, it ascends to the region located behind the ear. This position is significant because it is where the channel connects to the heart, symbolizing the integration of emotional and physical health. The locations of divergence in these channels often correlate with their functional roles in the body, and understanding this pathway helps practitioners address deeper systemic imbalances.

The other options mentioned do not accurately represent the emergence point of the PC divergent channel, as each serves distinct anatomical or functional roles within the body.
