在神精细胞的轴突里,发生细胞内的粒子及分子经常的流动。此流动被称为“轴突原浆的运输”,对于它的调查研究,视路提供给生理学家一个方便的实验的系统。用酶记分器及自动放射线照相术,证实在视网膜节细胞轴突内有直行的轴突原浆的流动的快相及慢相,用同样的技术表明,在外膝状体内的突触的末梢及位于视网膜内层的核周围部之间,也发生逆行的轴突原浆的流动。虽然它依赖氧化的代谢,在轴突与核周围部之间,轴突原浆的流动不需要物理的连续性;轴突的运输局部地控制在轴突之内,并由于压碎或缺血而神经纤维局部的中断引起断端双侧的小器 In the divine sperm axons, intracellular particles and molecules often flow. This flow is known as “transport of axonal pulp”, and for its investigation, the visual pathway provides physicians with a convenient experimental system. Using an enzymatic log and autoradiography, it was demonstrated that the fast and slow phases of the flow of axonal plasma directly in the axons of the retinal ganglion cells demonstrated with the same technique the synaptic terminals in the geniculate bodies Retrograde axonal flow also occurs between the perinuclear parts of the inner retina. Although it relies on oxidative metabolism, the flow of axonal pulp does not require physical continuity between the axons and the perinuclear portion; the transport of axons is locally controlled within the axons and due to crushing or ischemia The local nerve fiber interrupt caused by the two sides of the small device
