The Twelve Regular Meridians(2)
2. Rules of Distribution
The distributions of the twelve regular meridians on the body surface are fixed. For example, in the limbs the yin meridians are over the medial aspect, and yang meridians, lateral aspect. Each limb is supplied by the three yin and yang meridians distribution. On the whole, the anterior border is supplied by the Taiyin and Yangming Meridians; the posterior border, by Shaoyin and Taiyang Meridians; the midline by Jueyin and Shaoyang Meridians. On the face and head, the face and forehead are distributed by Yangming Meridians; the check, vertex and hindhead are passed by Taiyang Meridians; and the Shaoyang Meridians travel along the lateral aspect of the head. On the body trunk, the three yang meridians of the hand run through the scapular regions. Among the three yang meridians of the foot, the Yangming Meridian runs anteriorly (from chest to abdomen); the Taiyang Meridian, posteriorly (along the back); and the Shaoyang Meridian, laterally. The three yin meridians of the hand all emerge from the area below the axilla, whereas three yin meridians of the foot run through the abdominal regions. The sequence of meridians in passing through the abdominal region from the interior is firstly the Foot Shaoyang, secondly the Foot Yangming, thirdly the Foot Taiyin, and fourthly the Foot Jueyin Meridians.
3. Interior-Exterior Relationships
There are sixpairs of meridians of "exterior-interior correspondence" which are comprised of the three yin and three yang meridians of the hand and foot and communicate through the divergent meridians and collaterals. Chapter 24 in Plain Questions states: "The Meridians of Foot Taiyang and Shaoyin, the Meridians of Foot Shaoyang and Jueyin, and the Meridians of Yangming and Taiyin are exteriorly-interiorly related respectively. ¡°Indicated here is that the yin and yang of foot, the Meridians of Hand Taiyang and Shaiyin, the Meridians of Hand Shaoyang and Jueyin and the Meridians of Yangming and Taiyin are all exteriorly-interiorly related, and refers to the yin and yang of the hand.
The two interior-exterior meridians connect at the end of the four extremities which respectively run along the medialateral aspects of the four limbs (the Liver Meridian of the Foot-Jueyin crosses with the Spleen Meridian of Foot-Taiyin at spot eight cun above the medial malleolus, after which those two meridians exchange their positions, the Taiyin on the anterior border and the Foot Jueyin in the midline). Separately these meridians which are communicating with the interior-exterior viscera, manifest in the Foot Taiyang Meridian which pertains to the urinary bladder and communicates with the kidney; and the Foot Shaoyin Meridian which pertains to the kidney and communicates with the urinary bladder.
The interior-exterior relationships of the twelve regular meridians not only strengthen communication by the connection of the two interior-exterior meridians, but also connect with and pertain to the same viscera. This enables the zang-viscus and fu-viscus with the interior-exterior relationship to be inter-coordinating in physiological function, and inter-influencing in pathology. For example, the spleen dominates transportation and transformation and is in charge of sending up the clear qi; the stomach dominates the reception and sending of the turbid qi downward; the heart-fire transmits into the small intestine, etc. In treatment, the points belonging to the two interior-exterior meridians can be mutually selected. For example, the points from the Lung Meridian can be selected to treat diseases of the large intestine viscera or also illnesses of the meridian.
4. The Order of Cyclical Flow
The twelve regular meridians are distributed over the interior and exterior body, and the qi and blood circulate endlessly in the meridians. Beginning in the Lung Meridian of the Hand Taiyin, and transporting to the Liver Meridian of the Foot Jueyin in proper order, this process then returns once more to the Lung Meridian.
