What Are Meridians in Traditional Chinese Medicine?
Meridians are the channels described in traditional Chinese medical accounts of the body. The general Chinese term 經絡 / 经络 (jīngluò) means channels and collaterals; 經脈 / 经脉 (jīngmài) refers to the main channel-vessels. An acupoint, 穴位 (xuéwèi) or 腧穴 (shùxué), is a different kind of term: it names a point rather than a whole channel. [1][2]
These terms describe a traditional framework. A channel's name or a standardised chart is not, by itself, evidence that its route is identical to a nerve, artery or other structure identified by modern anatomy. This page explains the vocabulary without giving routes, point locations or treatment instructions.
1. The terms: jīngluò, jīngmài and xuéwèi
English writing can compress several Chinese terms into “meridian.” Distinguishing them makes a description easier to read:
| Chinese | Pinyin | English used here | What it names |
|---|---|---|---|
| 經絡 / 经络 | jīngluò | channels and collaterals | The traditional network |
| 經脈 / 经脉 | jīngmài | channel-vessels | The main channels |
| 絡脈 / 络脉 | luòmài | collaterals | Branching connections within that account |
| 穴位 / 腧穴 | xuéwèi / shùxué | acupoints | Named points, rather than channels |
WHO's 2022 terminology standard describes the network and distinguishes the twelve regular meridians, extraordinary meridians and point categories. We use these terms as vocabulary, not as a guide to selecting or locating points. [1, section 3.5]
For the word qi itself, see What Does Qi Mean in Chinese Medicine?.
2. How the traditional texts describe the channels
The Lingshu, part of the Huangdi Neijing, contains chapters devoted to channel vocabulary. In Hai Lun, the text describes the twelve channels as connecting inwardly with the organs and outwardly with the limbs and joints. This is a paraphrase of the Chinese passage, not a clinical conclusion. [3]
That passage helps explain what the framework is trying to describe: relationships between different parts of the body. A historical source can document that description without establishing that every relationship in it corresponds to a distinct structure visible in imaging or dissection.
The twelve regular channel names combine several kinds of information. The names specify hand or foot, a yin/yang division, and an associated organ label. A 2023 terminology article by Lee, Ryu and Chae explains why shortening a full name to an organ word loses some of that information. Its clinical proposals are separate from the naming point used here. [2]
3. A channel chart is not an anatomical drawing
A channel chart organises the names and relationships of a traditional account. An anatomical drawing organises identified bodily structures. Before interpreting a line on either kind of image, ask what the image claims to represent and how that claim was established.
For example, the label “Lung channel” tells you its place in the channel vocabulary. It does not mean that the line is lung tissue or that the chart shows a tube made of lung tissue. Likewise, a dot labelled with an acupoint name does not become a self-treatment instruction simply because it is printed on a body outline.
4. Traditional accounts and modern research are different questions
Keep three questions separate:
- Terminology: What is a channel or point called?
- Anatomy: What structure, if any, is a particular study proposing as its counterpart?
- Clinical outcomes: What happened when a defined intervention was tested for a defined outcome?
An answer to one question does not automatically answer the others. Standardising a name makes communication more consistent; it does not demonstrate a mechanism. A study of an intervention also does not, by itself, prove every traditional route on a chart.
The practical reading test is to look for the extra step in the argument. If a page moves from a traditional term to “science has found this,” it needs an identifiable study, a clear account of what was measured, and an explanation of how that result supports the claim.
5. Reading the English name
This site uses “meridians” alongside “channels and collaterals” because readers encounter both. An English label should not hide the structure of the Chinese term or add an unexplained physical claim.
“Energy lines,” for example, adds a particular interpretation of qi. It is more useful to ask what a source means by qi and which Chinese channel term it is translating than to assume that the phrase names a measurable kind of energy.
The table below uses explanatory English renderings. Exact wording and word order differ between translations; the WHO entries provide one named standard for comparison. [1][2]
6. Three common misunderstandings
“There are only twelve terms to learn.” Twelve refers to the regular channels. The same terminology standard separately describes eight extraordinary meridians and other categories. [1, entries 2909 and 2926]
“The organ word is the whole name.” “Liver” omits the foot and Jueyin parts of the full channel name. An organ association is not an identification of the channel with that anatomical organ. [2]
“A standard name validates a treatment.” Naming, anatomy and clinical evidence are different questions. Use Acupuncture and Acupressure for the practice vocabulary and Traditional Use vs Scientific Evidence for evidence-reading questions.
7. What this page does not do
This is a language and context guide. It gives no channel routes, point coordinates, diagnosis or treatment recommendation. For organ terminology, continue to zang-fu and translation.
Key material

| 足厥陰肝經 / 足厥阴肝经 | zú juéyīn gānjīng | Foot Jueyin Liver channel |
| This is a vocabulary table. It does not give locations, routes or a way to choose a treatment. The pericardium and sanjiao names also illustrate why the twelve-channel list should not be treated as a list of twelve modern anatomical organs. |
