Course
This channel starts from the heart, comes out of the cardiac system (the large vessels connecting with other visoera and descends through the diaphragm to connect with the small intestine.
The branch of the channel sprouts from the cardiac system, runs upwards along the side of the throat,and joins the ocular connectors (the structures connecting the eyeball with the brain, including blood vessels and optic nerves).
The original channel ascends to the axilla. And then it travels along the posterior border of the medial aspect of the upper arm, passes behind the Lung Channel of Hand-Taiyin and the Pericardium Channel of Hand-Jueyin. Goes downwards and reaches the cubital fossa. It continues to run along the posterior border of the little finger reaches the tip (Point Shaochon, HT9), and finally connects with the Small Intestine Channel of Hand-Taiyane.
