十二經(jīng)脈的循行走向與銜接規(guī)律

    十二經(jīng)脈的循行走向總的規(guī)律是：手三陰經(jīng)從胸走手，手三陽經(jīng)從手走頭，足三陽經(jīng)從頭走足，足三陰經(jīng)從足走腹胸。

    十二經(jīng)脈循行銜接規(guī)律是：①相表里的陰經(jīng)與陽經(jīng)在手足末端交接。如手太陰肺經(jīng)與手陽明大腸經(jīng)交接于食指。②同名的陽經(jīng)與陽經(jīng)在頭面部交接。如手陽明大腸經(jīng)與足陽明胃經(jīng)交接于鼻旁。③相互銜接的陰經(jīng)與陰經(jīng)在胸中交接。如足太陰脾經(jīng)與手少陰心經(jīng)交接于心中（見表1-3）。
