If you feel the patella, you can tell it's artificial.

如果摸到髌骨，就知道是人造。

A strike to your patellar tendon triggers an electrical impulse that travels up a sensory neuron to your spine.

敲击你髌骨肌腱会触发电子脉冲。该脉冲将沿着感觉神经元上传到你脊椎。

I broke all five metatarsals across the top of my foot, did a Lisfranc fracture which is that this part of the foot.

我脚上所有五个髌骨都骨了，做了利弗兰奇骨手术，也就是脚这部分。

An average human body contains 206 bones, ranging in shape and size from the tiny stapes of the inner ear to the huge femur of the thigh.

一个人平均身体包含 206 块骨头，形状和大小从内耳微小髌骨到大大股骨不等。

Sesamoid bones are small bones in tendons where considerable pressure develops, for instance, in the wrist. These, like sutural bones, are also variable in number. Two sesamoid bones, the patellas (kneecaps) are present in all individuals.

籽骨是肌腱中小型骨，肌腱中会产生相当大压力，例如在腕部。这些骨像缝间骨一样，在数量上是可变。两块籽骨——髌骨（膝盖骨）存在于所有个体中。

When we tap your, let's say your patellar tendon that causes a stretch in a muscle spindle, this sends a signal back to the sensory neuron, which activates a motor neuron in the spinal cord to cause your knee to kick up.

当我们敲击你，比方说你髌骨腱，它会导致肌肉纺锤体拉伸，这会向感觉神经元发送信号，这会激活脊髓中运动神经元，使你膝盖抬起。
