The Arm Jue Yin Pericardium Meridian. It starts from the chest from the pericardium and runs down along the diaphragm to connect with the Triple Burner Meridian. It has two branches: one from the chest travels to the armpit and along the middle part of the upper arm, down between the lung and heart channels to the elbow crease. It continues down the forearm and enters the palm where it ends at the tip of the middle finger. A second branch emerges from the palm and connects with the Triple Burner Meridian at the end of the ring finger. Imbalance in the Pericardium Meridian presents itself as symptoms of heart pain, palpitations, chest discomfort and "shen" disorders such as manias.
