查询词典 afferent

The superficial laminae of the spinal dorsal horn, especially lamina II which is composed mainly of small interneurons, receive primary afferent C fibers which transmit peripheral noxious information, and descending projection fibers from central endogenous antinociceptive system.

This review and our recent studies suggest that:(1) baroreceptor reflex is blunted in heart failure;(2) central angiotensin Ⅱ and reactive oxygen species play an important role in blunted baroreceptor reflex;(3) cardiac sympathetic afferent stimulation and chemoreceptor reflex inhibit baroreceptor reflex; and (4) exercise training normalizes abnormal reflexes in the heart failure state.

本综述及我们近年的研究表明：(1)在心力衰竭状态下压力感受性反射功能明显减弱；(2)中枢血管紧张素Ⅱ和活性氧在压力感受性反射功能失调中发挥关键作用；(3)心交感传入刺激和化学感受性反射能抑制压力感受性反射；(4)适当的运动可以部分纠正异常的心血管反射活动。
