One of them, the ulnar nerve, is particularly relevant for our purposes.

其中之一，尺，与我们要谈论的内容特别相关。

Your ulnar nerve is composed of both sensory and motor nerve fibers.

尺由感觉和运动纤维组成。

So that's how your ulnar nerve generally works.

这就尺的一原理。

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

我要找到你的尺，大概在这个位置。

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配。

Ulnar nerve entrapment is a relatively common condition.

尺卡压一种比较常见的疾病。

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

这会造成正中与尺功能障碍，因为这两条含有来自C8、T1根的纤维。

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配。

It happens when the ulnar nerve becomes compressed and obstructed, most commonly with the cubital tunnel.

它发生在尺受到压迫和阻塞时，最常见的在肘管位置。

But your elbow has an anatomical quirk that leaves your ulnar nerve vulnerable to getting activated in a different way.

但肘部有一个结构上的怪异表现，这使得尺很容易以不同的方式得到激活。

Damaged his ulnar nerve, was misdiagnosed as carpal tunnel.

他的尺受损, 被误诊为腕管。

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

肱骨内髁部可能非常痛苦的伤害，通常暂时的，但你有尺骨。

In addition to these more immediately distressing moments, regular bent-elbow activities are thought to put pressure on the ulnar nerve over time.

除了这些更直接的痛苦时刻外，频繁弯曲肘部活动会随着时间的推移对尺施加压力。

The result of this chronic ulnar nerve pain can be persistent paresthesia, as well as weakness in the forearm and hand.

这种慢性尺疼痛的可能会带来持续的异常感觉，同时小臂无力，手无力。

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.

所以尺受损会导致小指运动障碍及四指外展内收障碍。

Instead of the sensation simply activating peripheral receptors that send electrical signals along your ulnar nerve, the nerve's fibers are stimulated directly.

这种感觉不简单地激活沿尺发送电信号的外周感受器，而直接刺激纤维。

Sensory receptors in your pinky finger's tissues register that unfortunate information and send electrical impulses up the ulnar nerve, which are then processed in your central nervous system.

小拇指组织中的感觉感受器记录下这一不幸的信息，并向尺发送电脉冲，然后在中枢系统进行处理。

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，尺配小鱼际肌，控制小指运动，并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.

麻筋儿这种感觉当你击中尺时产生的，它非常浅，因为它围绕着你上臂骨的内上髁。

That includes stretching your arms and straightening your elbows, and generally taking breaks that help provide regular relief and maximal blood flow to your ulnar nerve.

这包括伸展手臂、伸直肘部动、惯常休息，有助于为尺提供规律放松以及最大程度的血液。
