单词 Thenar muscle
释义

Thenar muscle

原声例句
Osmosis-神经

In severe situations, the thenar muscles at the base of the thumb can start to waste away.

在严重的情况下,拇指底部的肌肉会发生萎缩。

Osmosis-神经

Now moving on to the hand, the median nerve innervates the thenar muscles which control the movements of the thumb, so thumb movements are limited.

现在看看对手部的影响,正中神经支配大鱼际肌,控制大拇指运动,因此正中神经受损时,拇指运动受限。
