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.

麻筋儿这种感觉是击中尺神经时产生的，它非常浅，因为它围绕臂骨的髁。

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.

弯曲肘部时，尺神经会扁平地侧髁，该区域的保护组织发生移位，使尺神经特别接近皮肤表面。

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.

但是尺神经到达肘部时，它下穿肱骨底部（也被称为髁）的骨隆位置，穿行经韧带和肌肉组织的隧道（即肘管）。
