The other side of the ring finger and pinky are served by the ulnar nerve.

环指尺侧半和小指由尺经支配。

So I'm gonna find your ulnar nerve, which is probably right around here.

我要找到你的尺经，大概在这个位置。

This leads to dysfunction of the median and ulnar nerves since they contain fibers from these roots.

这会造成正中与尺经功能障碍，因为这两条经含有来自C8、T1经根的经纤维。

The other side of the ring finger and the pinky are innervated by the ulnar nerve.

无名指另一侧及小指由尺经支配。

The funny bone can be a very painful injury and it's usually very temporary but what happens is you have an ulnar nerve.

肱骨内能是非常痛苦的伤害，通常是暂时的，但是你有尺骨经。

So an injury to the ulnar nerve causes a loss of movement of the little finger and the inability to abduct or adduct all 4 fingers.

所以尺经受损会导致小指运动障碍及四指外展内收障碍。

Similarly, the ulnar nerve supplies the hypothenar muscles which control the little finger, the interossei muscles which abduct and adduct the fingers, meaning to spread or bring them together.

同样，尺经支配小鱼际肌，控制小指运动，并支配骨间肌控制手指外展内收，即伸展或聚拢手指。

The funny bone sensation is when you actually hit the ulnar nerve, which is pretty superficial right here as it comes around the medial epicondyle of your upper arm bone.

麻筋儿这种感觉是当你击中尺经时产生的，它非常浅，因为它围绕着你上臂骨的内上。
