RESUMEN
The one-to-one correspondence between auricular points and internal organs is due to the existence of primitive stress system inside human body. The primitive stress system consists of gap junction intercellular communication pathways which transport small molecules to support the development of embryo prior to the formation of cardiac vessels. When embryo is mature, this transportation function enters into a resting state and will only be triggered when cells receive nociceptive stimulations. After the injured cells are repaired or replaced, the relevant pathways will rest again. The discovery of the primitive stress system not only explains the phenomenon of the correspondence between auricular points and internal organs, opening a new way of exploring the phenomena of body acupoints, but also develops a novel field in the research of bioscience.
