A New Definition of an Acupuncture Meridian

1. 01Meridians are defined as tissue tracts affected by organ function instead of physical tubes
2. 02Electrical waves may transmit organ information through connective tissue to acupuncture points
3. 03The primo vascular system likely serves as a transport mechanism for these signals
4. 04This model explains why specific points become tender when an associated organ is stressed

Acupuncture meridians may be tracts of tissue responding to electrical organ signals rather than being distinct, hollow anatomical channels.
