神经活动所需的大量蛋白质主要在尼氏体合成，再流向核内、线粒体和高尔基复合体。当神经元损伤或中毒时，均能引起尼氏体减少,乃至消病毒。若损伤恢复除去有害病毒素后，尼氏体又可恢复。病毒此，尼氏体的形态结构可作为判定神经元功能状态的一种标志。

2）神经原纤维：在神经细胞质内，存在着直径约为2～3μm的丝状纤维结构，在银染的切片体本可清晰地显示出呈棕黑色的丝状结构，此即为神经原纤维，在核周体内交织成网，并向树突和轴突延伸，可达到突起的未消部位。在电镜下观察，神经原纤维是由神经丝甜神经微管集聚成束所构成。神经丝或称神经细丝，是直径约为10nm细长的管状结构，是中间丝的一种，但与 其他细胞内的中间丝有所不同。在电镜高倍放大观察。可见神经细丝是极微细的管状结构，中间透明为管腔，管壁厚为3nm，其长度特长，多集聚成束。分散在胞质内，也延伸到神经元的突起中。神经丝的生理功能是参与神经元内的代谢产物和离子运输流动的通路。神经微管是直径约25nm的细而长的圆形细管，管壁厚为5nm，可延伸到神经元的突起中，在胞质内与神经丝配列成束
，交织成网。
其生理功能主要参与胞质内的物质转运活动，接近微管表面的各种物质流速zui大，微管的表面有动力蛋白，它本身具有ATP酶的作用，在ATP存在状态下，可使微管滑动，从而使微管具有运输功能。此外，还有较短而分散的微丝。微丝是zui细的丝状结构，直径约5nm，长短不等，集聚成束，交织成网，广泛的分布在神经元的胞质和突起内，其主要功能具有收缩作用，适应神经元生理活动的形态改变。神经丝、微管、微丝，这三种纤维，构成神经元的细胞骨架，参与物质运输，在光镜下所显示仅是神经丝和神经微管形成的神经原纤维。
A large number of proteins required for neural activity are mainly synthesized in the Nissl body, and then flow to the nucleus, mitochondria and Golgi complex. When the neurons damage or poisoning, can cause reduction of Nisshin, and even eliminate the virus. If the damage recovery to remove harmful toxins, Nissl can be restored. This virus, the microstructure of Nisshin can be used as a marker to determine the functional status of neurons.

2) Neurofibrils: In the cytoplasm of the nerve, there is a filamentous fibrous structure with a diameter of about 2 to 3 μm. The stained body of the silver stained body can clearly show a brown-black filamentous structure, that is, a neuron Fiber, in the perinuclear body intertwined into a network, and to the dendrites and axons can reach the outstanding part of the protrusion. Observed by electron microscopy, neurofibrils are composed of neuromuscular microtubules gathered into bundles. Neurofilament or nerve filaments, is about 10nm in diameter elongated tubular structure, is a kind of intermediate silk, but with other cells within the intermediate silk is different. High magnification in the electron microscope observation. Visible nerve filaments are very fine tubular structure, the middle of the lumen is transparent, the tube wall thickness of 3nm, its length of expertise, and more gathered into bundles. Dispersed in the cytoplasm, but also extends to the protuberances of neurons. The physiological function of neurofilaments is a pathway that participates in the flow of metabolites and ions within neurons. Nerve microtubules are thin, long, circular, thin tubes of about 25 nm in diameter with a wall thickness of 5 nm that extend into the protuberances of neurons and are arranged in bundles with the neurofilaments in the cytoplasm
, Interwoven into a network.
Its physiological function is mainly involved in the transport of substances in the cytoplasm. The flow velocity of various substances close to the surface of the microtubule is the largest. The microtubule has the motive protein on the surface, which itself has the function of ATPase. Under the presence of ATP, Sliding, so that the microtubules have a transport function. In addition, there are shorter and scattered microfilaments. Microfilament is the thinnest filamentous structure, about 5nm in diameter, ranging in length, gathered into bundles, woven into the network, widely distributed in the neurons of the cytoplasm and protrusions, the main function of contraction, to adapt to neuronal physiology The shape of the activity changes. Neurofilaments, microtubules, microfilaments, these three kinds of fibers, constitute the cytoskeleton of neurons, involved in material transport, in the light microscope shows only the nerve fibers and nerve microtubules formed by the nerve fibers.
