神经元的突起是神经元胞体的延伸部分,由于形态结构和功能的不同,可分为树突(dendrite)和轴突(axon);树突是从胞体发出的一至多个突起,呈放射状。轴突每个神经元只有一根胞体发出轴突的细胞 质部位多呈圆锥形,称轴丘,其中没有尼氏体,主要有神经原纤维分布。
神经毡中可见树突和轴突不同程度水肿,尤其是树突呈现极度扩张形成不规则的“气球”,其中含有许多大小不等的薄膜空泡。
The axons and even the dendrites were dilated extremely to form irregular "balloon" which contained different vacuoles in size and distorted the structure of neuropil.
TCP 神经元的树突通常分别与轴突末端和突触前树突形成轴突突触和树突突触。
The dendrites of the TCP neurons usually make axodendritic synapses and dendrodendritic synapses with axonal terminals and presynaptic dendrites, respectively.
卡哈尔在用胚胎观察神经组织时,发现轴突和树突是从胞体上生出的。
Cajal examined nervous tissue from embryos, and noticed that the axon and dendrites grow out of the cell body of the neuron.
Between any neurons, between the axon of one neuron and the dendrite of another, there's a tiny gap.
在神经元之间,在一个神经元的轴突,和另一个神经元的树突之间,有一个细小的缝隙
You want decisions to be made there so you need some additional mechanism for decision making at the point of contact between the axon of one cell and the dendrite of another.
而想要做出决定,在一个细胞的轴突和下一个细胞的树突,的连接点上 需要额外的决策机制
Well, that specialized region - now in this diagram here, this is the axon of one cell, the first cell in a sequence and that axon meets the dendrite of another cell at a special region called a synapse.
图中这里的这一特定区域,是一个细胞的轴突,是这一列中的第一个细胞,而轴突,和另一个细胞的树突,在一个叫做突触的地方相遇
