thenar eminence 指手掌拇指根部的隆起部位,由拇指球肌群构成,主要负责拇指的对掌、外展、屈曲等精细动作。(也常译为“鱼际隆起/大鱼际”。)
/ˈθɛnɑːr ˈɛmɪnəns/
The cut was just below the thenar eminence.
伤口就在拇指根部的鱼际隆起下方。
Weakness in the thenar eminence can make it hard to pinch or grasp small objects, which is sometimes seen with median nerve compression.
鱼际隆起无力会让捏取或抓握小物体变困难,这种情况有时见于正中神经受压。
thenar 来自希腊语 thēnar,意为“手掌(尤其是拇指根部)”;eminence 源自拉丁语 eminentia,意为“突起、隆起”。合起来就是“拇指根部的隆起”。
