Effect of somatic afferent nerve-visceral nerve circuit in the regulation of the gastrointestinal function with acupuncture and moxibustion
The distribution of the common acupoints of acupuncture-moxibustion for gastrointestinal diseases conforms to the rule of the segmental homology of somatic afferent nerve-visceral nerve circuit at the spinal cord level.Acupuncture-moxibustion regulates the gastrointestinal function through the nerve-endocrine-immune system,and especially depending on the integrity of the structure and function of nervous system.The somatic afferent nerve-visceral nerve circuit plays an important role in the process of acupuncture and moxibustion for regulating the gastrointestinal function.There are three dimensions.① The somatic afferent nerve-visceral nerve circuit at the peripheral level,including the somatic afferent nerve-visceral afferent nerve circuit centered on the dorsal root ganglion,and the somatic afferent nerve-visceral efferent nerve circuit centered on the sympathetic ganglia;② that at the spinal cord level;③ that at the supra-spinal cord level,focusing on the various reflex circuits with the solitary nucleus involved.The somatic afferent nerve-visceral nerve circuit at the spinal level and inferior to it determines the segmental regulation of acupuncture-moxibustion in the gastrointestinal system,while that at the level superior to the spinal cord determines the supersegmental action of acupuncture-moxibustion in regulating the gastrointestinal system.The neurophysiological mechanism of acupuncture-moxibustion is multi-circuits and multi-targets in regulating gastrointestinal function.
