Hello everyone, we have previously discussed theory of organs In the next two classes, we will focus on the theory of meridian First let’s take a look at a video What deep impressions do you have on the video? I cannot understand why the patients open their eyes when taking operation Thoracic surgery like this should be under anesthesia In fact, in the movie the patient did not use anesthetics, but acupuncture anesthesia methods. The patients undergo surgery soberly It can not only reduce the side effects of anesthetics, but also save surgery time, It does not require postoperative recovery, More importantly, it can avoid some of the problems during the postoperative respiratory function recovery in the digestive system Reduce this burden on the patients Why acupuncture can play such a role? As early as 2000 years ago, the Chinese have recognized human body through meridians There are a lot of points above the meridian distribution Acupuncture can be generated by a series of analgesic effect Of course, there also includes acupuncture anesthesia Therefore, the focus of this lesson will be on the concept and function of the meridian First, let's talk about the classification and names of Meridian The body's meridians can be roughly divided into "meridians" and "collaterals" To put it easily "Meridian" is "main" distributed in the human body's meridians And collaterals are "trails", but they are connected with each other. Today we primarily focus on the twelve meridians We can see that the body's arms, legs, the Chinese medicine calls hands and feet each has six meridians, where three are yang, three are Yin, They are together known as the twelve meridians, which in fact, are twenty-four, Because people are symmetrical, so in fact there are twelve. So we first take a look at what elements Meridian has. There are Taiyang, Shaoyang, Taiyin, Shaoyin, Yangming, Jueyin, and internal organs and hollow viscera. Good, you take a careful look. Well, remembering the names of the twelve meridians in fact means remembering the approximate location of the organs and the network. So, we take a look at the distribution of meridians on the body of hands and feet It basically has such an order. If u stretch your hands The Taiyin meridian should be in the inside of the outer edge of the hand. The middle one is called Jueyin A bit lower, the one in the inner side of ur hand is called Shaoyin Then get down to the backside, Shaoyin is next to the Taiyang In the middle, Shaoyang, outside, Yangming So you can see, three Yin inside and three Yang outside Then we'll see what organs they correspond to According to this, one meridian corresponds to one organ. It is too simple. If in the name there appeared organs, it indicates that it belongs to the organ, But it also contacts with the exterior of the internal organs For example, hand lunar lung, it belongs to the lungs, but it also contacted the large intestine. Because it is connective to the large intestine and lungs. In fact, the twelve meridians are actually in a certain order connecting each other. This will relate to circulation and distribution of the Meridians. The circulation of the twelve meridians begins from lung channel of hand Taiyin. Yin and Yang meridians link with each other and link end-to-end, transmitting through every meridian till to the liver meridian. Then a circulation system which is continued and moved constantly is formed. So what is the circulation? The traditional Chinese medicine holds that it is Yin and Yang making up blood which is the substance, message and energy of human body Just as mentioned in Miraculous Pivot: Ni Shun Fei Shou. Three Yin in hands moves from chest to hand; three Yang in hands moves from hands to head. Three Yang in feet moves from hands to feet; three Yin in feet moves from feet to belly. Then they connect human body and viscera as a whole. In addition to the twelve meridians, what are the other important meridians? That are “eight extra channels”. Besides, Chong, Ren and Du Channels are relatively more important. The distribution of “eight extra channels” is not as regular as the twelve meridians. They have no direct collateral connections with viscera, and they are not consistent with each other in exterior and interior. If you have interests, you can refer to some boos like the basis of traditional Chinese medicine to have more understandings. So what are the functions of meridians? We can conclude in four sentences The first one is to connect tissue and organ and link up the exterior and interior and ups and downs This emphasizes it connect the human body as a whole from structure The second aspect is current of Qi and blood, Yin and Yang This is about one of its important functions The third aspect is reaction and conduction The forth aspect is that it can adjust functional activity of human body 可以通过经络的针刺等等来调节人体的功能 Through the acupuncture of meridians can the function of human body be adjusted. It is relatively easy to understand “connect tissue and organ and link up the exterior and interior and ups and downs” Then you have mentioned that the twelve meridians are corresponding to each viscera in human body And we also have learned the viscera is separately corresponding to the five systems like eyes and ears This may be the meridian system So we want to know how to understand the current of Qi and blood, Yin and Yang We know that blood flows in blood vessel, how does it flow to the meridians? This question is difficult to answer. Because the essence of meridians still remains a difficult question in the world. My personal view is, the ancient people’s view on the meridians were based on function just like defining the viscera. We have talked before the definition of viscera starts form the aspect of function So how about the meridians? Broadly speaking, they include the tangible tissues like blood vessel, lymph and nerves, so they have the function to go through the Qi and blood, Yin and Yang. But meridians are not equal to these tissues, because it still has other activities, like reaction, conduction and regulation and so on. Let’s see an example When the patient with toothache accepts the acupuncture in Hegu point, it has good analgesic effect. But it can not be detected in anatomy. This acupuncture point has connections with any lymph, nerve and blood vessel. So the acupuncture can not only detect the proximal treatment, but also some remote treatments like the examples we have mentioned just now. This clearly indicate that, often there are no relation between blood vessel lymph and nerve. So what is the essence of meridians? We will talk about this question next class. This is all for our class today. So next class we will talk the essence of meridians together.
