以往关于神经原的突触组成理论,主要认为由一个神经原的轴突终末支或其侧支的终末支,与另一个神经原的树突或者直接与细胞体的表面接触而成.1934年西班牙神经组织学家Cajal氏将中枢神经系统内的突触分成二类:轴体突触和轴树突触.我国神经生理学家张香桐(1956)将此二类突触分别称为胞体上的突触或包围性突触和树突上的突触或依傍性突触.但是,学者对突触的研究方面一直都集中在神经原本身间突触的构造上,而对神经原与其周围组织间的联系,特别是与围绕神经原的血管的联系的研究是非常少的. ??氏在1954年指出,“在机体生存的各种条件下,神经原间突触和神经——组织的
Previous synaptic composition theory about neurons, mainly by the terminal axon of a neuron or its collateral terminal branch, and another neuron dendrites or direct contact with the surface of the cell body made. In 1934, Spanish neuroscientist Cajal’s classifies synapses in the central nervous system into two categories: Axis synapses and Axon dendrites.Chinese neurophysiologist Zhang Xiangtong (1956) described these two types of synapses as cell bodies Of synapses or surrounded by synapses and dendrites on the synapse or by the synapses.However, scholars have been focused on the synapses in the structure of the synapses in the nerve itself, while the neurons and the surrounding There is very little research into the relationship between tissues, especially the blood vessels around the neurons. “In 1954, he pointed out that” under various conditions of the organism, neuronal synapses and neuro-tissues of
