作者在用石蜡镀银法染色的猫眼外直肌的切片中,观察到下列的结果: 1.猫眼外直肌内有丰富的神经末梢。在单位面积中,神经末梢的数量比它的蚓状肌要多得多。 2.猫眼外直肌运动终板的大小和形状有很大的差异。根据形状可分为叉状运动终板、树枝状运动终板、花瓣状运动终板和爪状运动终板四种类型。少数已有运动终板的肌纤维,尚接受副末梢的供给。 3.和运动纤维伴行的细纤维,一部分是运动纤维的分支,它们参与运动终板的组成。有一些细纤维除开分支组成运动终板外,其本干穿出运动终板,末端形成梭状肿大,终止于其他的肌纤维。 4.猫眼外直肌的两端,紧靠肌腱的附近,存在着少数形态较简单没有结缔组织膜包被的肌膜。 5.猫眼外直肌内有很丰富的感觉末梢。葡萄状感觉末梢的数量最多,是眼外直肌最主要的本体感觉末梢;并且还有少量的肌梭和螺旋状感觉末梢。在结缔组织中,有游离感觉末梢、丝球状感觉末梢、树枝状感觉末梢和芽状感觉未梢。 6.Marsland,Glees和 Erikson的石蜡镀银法,是一个较简便而稳定的神经末梢的染色法。
The authors observed the following results in sections of the cat’s external rectus abdominis stained with a paraffin-silver method: 1. Cat’s eye outside the rectus abdominis is rich in nerve endings. In the unit area, the number of nerve endings than its vermicular muscle much more. Cat’s lateral rectus motor end plate size and shape are very different. According to the shape can be divided into fork-shaped motor end plate, dendritic end plate, petal-like motor end plate and claw-like motor end plate four types. A small number of muscle fibers have end-exercise board, still accept the supply of perilous. 3. The fine fibers associated with the movement fibers are, in part, the branches of the movement fibers that participate in the composition of the motor end plates. There are some fine fibers apart from the movement of the end plate composition, the stem out of the exercise endplate, forming a shuttle-shaped end, terminating in other muscle fibers. Cats at both ends of the lateral rectus abdominis, close to the tendon in the vicinity, there is a small number of forms without connective tissue membrane coated sarcolemma. 5. Cat’s eye outside the rectus abdominis has a very rich feeling. Grape-like sensory endings the largest number, is the most important off-body rectus proprioception end; and there is a small amount of muscle shuttle and spiral sensory end. In the connective tissue, there are free-feeling peripherals, silky-like sensory terminals, dendritic sensory terminals, and bud-like sensations. 6.Marsland, Glees and Erikson’s paraffin silver, is a more simple and stable staining of nerve endings.
