It goes from the region of the cell where the dendrites are down through the axon.
它从这个细胞的,树突顺流直下流向轴突
This part of the cell becomes depolarized because it gets the message that it's supposed to depolarize because of all the inputs that impinge on these dendrites.
这一部分细胞会去极化,因为它得到了,树突上接受到的神经冲动所传达的,要求它去极化的信息
Some terminology, some of which I've already given you: cell body, dendrites, axons.
我已经教给你们一些术语了,比如说细胞体,树突,轴突
Information flows from the dendrites, through the cell body, down the axon.
信息从树突发出,穿过细胞体,传至轴突
It's collecting information from all these dendrites under the right series of signals the cell body integrates all that information, says time for me to fire an action potential.
神经收集所有树突送来的,通过一系列正确信号传来的信息,细胞体整合所有信息之后,就到了发出动作电位的时候了
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
One is that there's a physical space in between the two cells, so the axon of what's called the pre-synaptic neuron, or the neuron that's bringing a signal into the synapse, the axon terminal is physically separated from the dendrite of the next cell.
一是两个细胞间有一定的物理空间,所谓的突触前神经元,也就是将信号传递到突触的神经元的,轴突的末梢,同下一个细胞的树突间被物理性分离开
So, the classes of T-cells: macrophages, natural killer cells, these are a class of cells that's particularly important called dendritic cells.
这类T淋巴细胞包括巨噬细胞,自然杀伤细胞等 统称为树突细胞,树突细胞尤为重要
