Scientifically, it is called cubital tunnel syndrome.

学上称之为肘管综合征。

So how does the median cubital vein run?

那么肘正中静脉是如何运行的呢？

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，尺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经区域。

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.

但是当尺经到达肘部，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）。

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

发生在尺经受到压迫和阻塞，最常见的是在肘管位置。
