The Body's Surface Zones: Where Meridians Reach the Skin

This unit has covered meridians, their branches, and their connecting channels. This lesson covers the outermost layer of all: the skin itself.
這個單元講過經絡、它的分支，還有它的連接通道。這一課要講的是最外層的那一層：皮膚本身。

Unit 111: The Body's Surface Zones: Where Meridians Reach the Skin

This unit's lessons on the twelve main meridians, the fifteen connecting channels, and the twelve sinew channels each described a progressively more surface-level layer of the meridian system, moving from deep pathway to muscle. The twelve cutaneous regions describe the final and most superficial layer of all: twelve zones of skin, each corresponding to one of the twelve main meridians, functioning as that meridian's outermost surface reach.

這個單元講十二正經、十五絡脈，跟十二經筋的那些課，各自描述了經絡系統一層比一層更表淺的層次，從深層的路徑一路講到肌肉。十二皮部描述的是最後、也是最表淺的一層：十二個皮膚區域，各自對應到十二正經的其中一條，扮演著那條經絡向外延伸到最表層的角色。

Because they sit at the very surface, the cutaneous regions are traditionally treated as the meridian system's first line of contact with the outside world — the layer an external pathogen, such as cold or wind, meets first, before it has any chance of moving into the sinew channels, then the connecting channels, and finally the main meridians themselves. A pathogen caught and repelled at this outermost layer, under this framework, never gets the chance to become the deeper problem an earlier lesson on hidden pathogens described lying dormant until a later season.

因為它們就位在最表層，十二皮部傳統上被當成經絡系統跟外界接觸的第一線——一個外來病邪，例如寒或風，最先遇到的那一層，還沒有機會往內移動到經筋、再到絡脈、最後到正經本身之前。在這個框架下，一個在這個最外層就被攔截、擊退的病邪，永遠沒有機會變成稍早講伏邪那一課描述過的、潛伏到之後一個季節才發作的更深層問題。

This layered structure — cutaneous region, sinew channel, connecting channel, main meridian, each one progressively deeper — gives the whole meridian system something this unit hasn't made explicit until now: a traditional model of how an external problem is expected to progress, layer by layer, if it isn't stopped early, mirroring the surface-to-core progression this course's four-layer fever model describes for warm disease specifically. Reading the skin itself as an active zone of the meridian system, rather than as a separate, purely cosmetic surface, is what makes catching a problem at this earliest and most superficial layer worth taking seriously.

這種分層結構——皮部、經筋、絡脈、正經，一層比一層更深——給了整個經絡系統一個這個單元到目前為止都沒有明講出來的東西：一個外來問題如果沒有及早被擋下來，傳統上被預期會一層一層往內推進的模型，呼應著這門課的衛氣營血四層發燒模型，專門為溫病描述的那種由表入裡的推進。把皮膚本身讀成經絡系統的一個活躍區域，而不是一個獨立、純粹外觀性的表面，正是讓在這個最早、最表層就攔截問題這件事，值得被認真看待的原因。

Questions · 閱讀理解

According to the passage, what are the twelve cutaneous regions?

Twelve zones of skin, each corresponding to one of the twelve main meridians, functioning as that meridian's outermost surface reach.

According to the passage, why are the cutaneous regions traditionally treated as the meridian system's first line of contact?

Because they sit at the very surface, meeting an external pathogen first, before it has a chance to move into the sinew channels, connecting channels, and main meridians.

According to the last paragraph, what does the layered structure of cutaneous region, sinew channel, connecting channel, and main meridian provide?

A traditional model of how an external problem is expected to progress layer by layer if not stopped early, mirroring the surface-to-core progression of the four-layer fever model.
