神经肌接头是了解突触传递的模型,这对麻醉医师熟悉肌松药更有特殊意义,本文将从这方面复习神经肌肉传递的生理学。一、神经肌接头的解剖运动神经进入肌肉后,再按肌肉功能继续分支,例如进行精细动作的肌肉,其神经支配肌纤维的数量就比较少,而调节姿势(体位)的有关肌肉,每根神经支配的肌纤维就比较多。人体除了眼部肌肉和某些面部、颈部肌肉外,其它肌肉都是由经管小范围的,
Neuromuscular junction is a model for understanding synaptic transmission, which is more specific to anesthesiologists who are familiar with muscle relaxants. This article reviews the physiology of neuromuscular transmission in this context. First, the anatomy of the neuromuscular motor nerve into the muscle, and then continue to branch by muscle function, for example, the fine motor muscle, the number of its innervated muscle fibers is relatively small, and adjust posture (posture) of the muscles, each nerve Dominate the muscle fiber is more. In addition to the human eye and some facial muscles, neck muscles, the other muscles are administered by a small range,
