孔两旁迎香穴而终焉。
[Formula Song] The upper part of the outer aspect of the arm and forearm is the Hand-Yangming Channel, the middle part is the Hand-Shaoyang Channel, and the lower part is the Hand-Taiyang Channel. The inner aspect of the arm and forearm is divided into three lines from top to bottom by the Hand-Taiyin Channel, the Hand-Jueyin Channel, and the Hand-Shaoyin Channel.
[Note] The outer aspect of the arm and forearm corresponds to the pathways of the Three Yang Channels of the Hand (Hand-Yangming Large Intestine Channel, Hand-Shaoyang Sanjiao Channel, Hand-Taiyang Small Intestine Channel). The upper portion belongs to the Hand-Yangming Channel, the middle portion to the Hand-Shaoyang Channel, and the lower portion to the Hand-Taiyang Channel. The inner aspect of the arm and forearm corresponds to the pathways of the Three Yin Channels of the Hand (Hand-Taiyin Lung Channel, Hand-Jueyin Pericardium Channel, Hand-Shaoyin Heart Channel). The upper portion belongs to the Hand-Taiyin Channel, the middle portion to the Hand-Jueyin Channel, and the lower portion to the Hand-Shaoyin Channel.
[Formula Song] The anterior aspect of the outer leg and knee is the Foot-Yangming Channel, the middle is the Foot-Shaoyang Channel, and the posterior is the Foot-Taiyang Channel. The inner aspect of the leg and knee is divided into three lines from anterior to posterior by the Foot-Jueyin Channel, the Foot-Taiyin Channel, and the Foot-Shaoyin Channel.
[Note] The outer aspect of the leg and knee corresponds to the pathways of the Three Yang Channels of the Foot (Foot-Yangming Stomach Channel, Foot-Shaoyang Gallbladder Channel, Foot-Taiyang Bladder Channel). The anterior portion belongs to the Foot-Yangming Channel, the middle portion to the Foot-Shaoyang Channel, and the posterior portion to the Foot-Taiyang Channel. The inner aspect of the leg and knee corresponds to the pathways of the Three Yin Channels of the Foot (Foot-Taiyin Spleen Channel, Foot-Jueyin Liver Channel, Foot-Shaoyin Kidney Channel). The anterior portion on the lateral side of the great toe and the middle portion on the medial thigh belong to the Foot-Jueyin Channel. The middle portion on the medial side of the great toe and the anterior portion on the medial thigh belong to the Foot-Taiyin Channel. The posterior portion wrapping around the ankle on the sole of the foot belongs to the Foot-Shaoyin Channel.
[Formula Song] The Hand-Taiyin Lung Channel originates above the breast, emerges laterally from the axilla, runs along the anteromedial aspect of the upper arm, reaches the elbow, follows the forearm into the Cun Kou pulse point, ascends to the Thenar eminence, and terminates at the medial border of the thumb.
[Note] The Hand-Taiyin Lung Channel originates at the end of the third rib above the breast, six cun lateral to the midline, from the anterior lateral curve of the axilla to the upper arm, from the anteromedial aspect of the upper arm to the elbow, along the medial forearm, passing the anterior edge, entering the Cun Kou, ascending to the Yu Ji point, and finally terminating at the medial side of the thumb, approximately the width of a leek leaf from the corner of the nail.
[Formula Song] The pathway of the Hand-Yangming Large Intestine Channel begins at Shang Yang point on the medial side of the index finger, runs along the lateral aspect of the hand, passes the elbow and upper arm, reaches the shoulder, enters the Que Pen region, ascends to the side of the neck, penetrates the cheek, descends into the lower teeth, exits at the Ren Zhong point, ascends alongside the nostrils, and terminates at the Ying Xiang point.
[Note] The Hand-Yangming Large Intestine Channel begins at the medial side of the index finger, approximately the width of a leek leaf from the corner of the nail, runs along the interosseous bone between the thumb and index finger, travels along the anterolateral aspect of the arm, passes the lateral elbow, from the upper arm to the shoulder, moves straight up from the Que Pen to the side of the head and neck, circles around the Ren Zhong point on both sides, and ends at the Ying Xiang point flanking the nostrils.
