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

我要找你的神经，大概在这位置。

But the impact alters the ulnar nerve's signaling, perhaps by causing a proliferation of nerve signals, leading to that intense pins-and-needles sensation called transient paresthesia, which radiates down the length of your arm.

但撞击改变了神经的信号，可能通过引起神经信号的增殖，导致一种强烈的针刺感，这种感觉被称为短暂的感觉异常，能够辐射手臂。

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神经时产生的，它非常浅，因为它围绕着你上臂骨的内上髁。

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，神经支配小鱼际肌，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。

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

这种感觉单地激活沿神经发送电信号的外周感受器，而直接刺激神经纤维。

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，但你有骨神经。

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

这会造成正中与神经功能障碍，因为这两条神经含有来自C8、T1神经根的神经纤维。

Ulnar nerve entrapment is a relatively common condition.

神经卡压一种比较常见的疾病。

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神经支配。

In this position, the ulnar nerve is covered only by skin and cubital tunnel ligament tissue, making it perhaps the longest area of semi-exposed nerve in your body.

这角度位置，神经仅被皮肤和肘管韧带组织覆盖，成为身体中最长的半暴露神经区域。

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.

所以神经受损会导致小指运动障碍及四指外展内收障碍。

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

环指侧半和小指由神经支配。

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

这种慢性神经疼痛的可能会带来持续的异常感觉，同时小臂无力，手无力。

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

神经由感觉神经和运动神经纤维组成。

But when your ulnar nerve reaches your elbow, it runs beneath the bony bump at the bottom of your humerus, named the medial epicondyle, and it passes through a tunnel of ligament and muscle tissue called the cubital tunnel.

但当神经达肘部时，它下穿于肱骨底部（也被称为内上髁）的骨隆位置，穿行经韧带和肌肉组织的隧道（即肘管）。

So that's how your ulnar nerve generally works.

这就神经的一般工作原理。

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幸的信息，并向神经发送电脉冲，然后在中枢神经系统进行处理。

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

但肘部有一结构上的怪异表现，这使得神经很容易以同的方式得激活。

When you bend your elbow, your ulnar nerve gets flattened against the medial epicondyle and the protective tissue in the area gets displaced, bringing the nerve especially close to the skin's surface.

当你弯曲肘部时，神经会扁平地贴于内侧髁上，该区域的保护组织发生移位，使神经特别接近皮肤表面。

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、伸直肘部动作、惯常休息，有助于为神经提供规律放松以及最大程度的血液。
