The detailed structure of nerve branches, neuromuscular junctions, and muscle fibers of a multiterminal innervation of cockroach abdominal muscle has been studied with the electron microscope. The muscle fiber is of the banded myofibril type; with paired mitochondria and abundant endoplasmic reticulum. The peripheral nerve branches are multiaxonal with large central axon and several small peripheral tunicated axons. Tracheoblasts closely accompany the nerve branches. The multiple neuromuscular junctions show typical axonal vesicles, muscle aposynaptic granules, and close plasma membrane apposition with no interposition of basement membrane material.
利用电子显微镜研究了蟑螂腹部肌肉多端神经支配的神经分支、神经肌肉接头和肌纤维的详细结构。肌纤维为带状肌原纤维类型,有成对的线粒体和丰富的内质网。外周神经分支是多轴突的,有大的中央轴突和几个小的外周有膜包裹的轴突。成气管细胞紧密伴随神经分支。多个神经肌肉接头显示出典型的轴突小泡、肌肉突触后颗粒以及紧密的质膜贴附,其间没有基底膜物质插入。
