神經(jīng)活動所需的大量蛋白質主要在尼氏體合成，再流向核內(nèi)、線粒體和高爾基復合體。當神經(jīng)元損傷或中毒時，均能引起尼氏體減少,乃至消病毒。若損傷恢復除去有害病毒素后，尼氏體又可恢復。病毒此，尼氏體的形態(tài)結構可作為判定神經(jīng)元功能狀態(tài)的一種標志。

2）神經(jīng)原纖維：在神經(jīng)細胞質內(nèi)，存在著直徑約為2～3μm的絲狀纖維結構，在銀染的切片體本可清晰地顯示出呈棕黑色的絲狀結構，此即為神經(jīng)原纖維，在核周體內(nèi)交織成網(wǎng)，并向樹突和軸突延伸，可達到突起的未消部位。在電鏡下觀察，神經(jīng)原纖維是由神經(jīng)絲甜神經(jīng)微管集聚成束所構成。神經(jīng)絲或稱神經(jīng)細絲，是直徑約為10nm細長的管狀結構，是中間絲的一種，但與 其他細胞內(nèi)的中間絲有所不同。在電鏡高倍放大觀察?？梢娚窠?jīng)細絲是極微細的管狀結構，中間透明為管腔，管壁厚為3nm，其長度特長，多集聚成束。分散在胞質內(nèi)，也延伸到神經(jīng)元的突起中。神經(jīng)絲的生理功能是參與神經(jīng)元內(nèi)的代謝產(chǎn)物和離子運輸流動的通路。神經(jīng)微管是直徑約25nm的細而長的圓形細管，管壁厚為5nm，可延伸到神經(jīng)元的突起中，在胞質內(nèi)與神經(jīng)絲配列成束
，交織成網(wǎng)。
其生理功能主要參與胞質內(nèi)的物質轉運活動，接近微管表面的各種物質流速zui大，微管的表面有動力蛋白，它本身具有ATP酶的作用，在ATP存在狀態(tài)下，可使微管滑動，從而使微管具有運輸功能。此外，還有較短而分散的微絲。微絲是zui細的絲狀結構，直徑約5nm，長短不等，集聚成束，交織成網(wǎng)，廣泛的分布在神經(jīng)元的胞質和突起內(nèi)，其主要功能具有收縮作用，適應神經(jīng)元生理活動的形態(tài)改變。神經(jīng)絲、微管、微絲，這三種纖維，構成神經(jīng)元的細胞骨架，參與物質運輸，在光鏡下所顯示僅是神經(jīng)絲和神經(jīng)微管形成的神經(jīng)原纖維。
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.
