关于脊椎动物运动神经终末与骨骼肌的关系早有报道,Tlegs等曾经指出不同动物的运动终极配布和形态不尽相同,而同一动物的不同肌群运动终板和分布和形态也各有特点,这与其所完成的功能不同有关。日前关于四肢肌的运动神经终末材料较多,而作为与呼吸和发声有关的喉内肌,对其研究甚少,尤其关于喉内肌运 As for the relationship between vertebrate motor nerve terminals and skeletal muscle, it has been reported that Tlegs et al. Have pointed out that the final motions and configurations of different animals are different, while the end-plates, distributions and morphologies of different muscle motions of the same animal also have their own characteristics , Which is different from its function. A few days ago on the limb muscles of the motor nerve terminal material more, and as breathing and sound related to the laryngeal muscle, little research on its, especially on the intrathoracic muscle transport
