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

我要找到你的经，大概在这个位置。

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.

但撞击改变了经的信号，可能是通过引起经信号的增殖，导致一种强烈的针刺感，这种感觉被称为短暂的感觉异常，能够辐射到整个手臂。

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.

麻筋儿这种感觉是当你击经时产生的，它非常浅，因为它围绕着你上臂的内上髁。

Finally, both the ulnar and median nerves innervate the lumbricals, which are 4 muscles that extend the fingers at the interphalangeal joints, and keep them flexed at the metacarpal phalangeal joints.

最后，经和正经都支肌，这四条肌能使指间关节的手指伸直，同时掌指关节保持屈曲位。

This is your ulna right here and this is your radius and what happens in people that require Tommy John surgery is they end up having a rupture of this tendon called the ulnar collateral ligament.

这是你的，这是你的桡，需要汤米·约翰手术的人是因为发生了肌腱断裂，称为侧副韧带。

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，经支小鱼际肌，控制小指运动，并支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.

这种感觉不是简单地激活沿经发送电信号的外周感受器，而是直接刺激经纤维。

Ulnar nerve entrapment is a relatively common condition.

经卡压是一种比较常见的疾病。

When the ulnar and median nerves get damaged, muscles in the forearm override the action of the lumbricals, causing the hand to look like a claw.

当经与正经受损时，前臂肌群的作用强于肌，造成手部呈爪型。

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

肱内髁部可能是非常痛苦的伤害，通常是暂时的，但是你有经。

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.

这个角度位置，经仅被皮肤和肘管韧带组织覆盖，成为身体最长的半暴露经区域。

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

这会造成正与经功能障碍，因为这两条经含有来自C8、T1经根的经纤维。

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.

经由感觉经和运动经纤维组成。

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经支。

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.

所以经受损会导致小指运动障碍及四指外展内收障碍。

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.

但是当经到达肘部时，它下穿于肱底部（也被称为内上髁）的隆位置，穿行经韧带和肌肉组织的隧道（即肘管）。

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

环指侧半和小指由经支。

So that's how your ulnar nerve generally works.

这就是经的一般工作原理。

Damaged his ulnar nerve, was misdiagnosed as carpal tunnel.

他的经受损, 被误诊为腕管。
