a long nerve fiber that carries signals away from the neuron's cell body
- 1.
一种神经纤维,是神经细胞的长而细的突起,将神经冲动从细胞体传导至突触。
A nerve fibre which is a long slender projection of a nerve cell, and which conducts nerve impulses away from the body of the cell to a synapse.
- 2.
从神经元细胞体向外传导的长神经纤维
long nerve fiber that conducts away from the cell body of the neuron
一种神经纤维,是神经细胞的长而细的突起,将神经冲动从细胞体传导至突触。;从神经元细胞体向外传导的长神经纤维;轴突;[计] 轴索
用法In use
Damage to an axon can slow the signals between brain cells.
用法提示:此处 axon 是名词,表示神经元中负责传导信号的轴突。

记忆技巧Memory Tip
想象神经细胞挥动斧头(ax)沿轴突砍出去,信号从细胞体‘on’向远方传导。
语境与语域Context & Register
语域:formal 常见场景:neuroscience textbooks、medical research reports 通常用于神经科学、医学等专业领域,比较常见于学术文章或教科书;日常口语中很少使用。
发音与拼写Pronunciation & Spelling
与 taxon 押韵(/-æksɑn/)。Saxon 和 klaxon 拼写中都含 -axon,但读作不重读的 /sən/,而不是 /sɑn/,所以与 axon 不押韵。oxen 是拼写上的近似词,读作 /ˈɑk.sən/,重读元音不同。
