针感与针刺效应机理探讨

Approach to Relation between Needling Sensation Response and Acupuncture Effects

从神经生理学角度探讨得气与针刺效应的关系。针刺一定穴位后 ,产生的针感途径是以躯体传入冲动为主 ,而通过躯体神经与植物神经在穴位下血管丛形成的汇合区 ,又引起内脏传入纤维发出的冲动对脏腑的调整功能。穴位传入信号与内脏器官发出的冲动在大脑皮层区又相互汇合 。

The relation between needling sensation response and acupuncture effects is explored from the view point of neurophysiology. After a needle is inserted into an acupoint, the needling sensation response is transmitted mainly by somatic afferent nerves,passing through the convergent area formed by autonomic nerves and somatic nerves and the vascular plexus under the acupoint and inducing the nervous impulse of visceral afferent nerves to adjust the function of internal organs. Then the afferent signals of acupoint and impulse from internal organs converage at the cerebral cortex, which is a basis of identity of acupuncture regulating function of internal organs and obtaining needling sensation.
