The spinal cord response is part of the micturition reflex.

脊髓反射是排尿反射的一部分。

Simultaneously, the internal urethral sphincter opens. This is called the micturition reflex.

同时，括约肌内壁开始打开。这叫做排尿反射。

As the urine collects in the bladder it increases the pressure on the bladder wall and the micturition reflex is triggered.

随着尿液在膀胱积累，膀胱壁受到的压力增高，触发排尿反射。

This is called the micturition reflex.

这称为排尿反射。

When you can't find a toilet and want to hold urine in, you activate the pontine storage center and that stops the micturition reflex.

当你找不到厕所，需要憋尿的时候，你的贮尿中枢将会兴奋，抑制排尿反射。

This sets off a reflex arc called the micturition reflex which causes contraction of the bladder and relaxation of the internal sphincter and external sphincter.

这就触发了一个反射弧，叫做排尿反射，导致膀胱收缩、尿道内外括约肌扩张。

If we want to delay urination, or hold it in, the pontine storage center overrides the micturition reflex, and when we want to urinate, the pontine micturition center allows for the micturition reflex to happen.

如果我们想要等会再尿或中止排尿，脑桥储尿中枢控制排尿反射；当我们想排尿时，脑桥排尿中心允许排尿反射发生。

When you finally do find that toilet, and you're ready to urinate, the pontine micturition center is active and it allows the the micturition reflex to happen - and you can finally pee.

当你终于找到厕所，准备好大尿一场时，排尿中枢兴奋，排尿反射发生——你就可以一泻千里了。

Finally, there are various conditions like diabetes, bladder cancer, Parkinson's, and multiple sclerosis, as well as procedures such as prostatectomy or hysterectomy that can damage the nerves involved with the micturition reflex, ultimately leading to urinary incontinence.

最后，还有多种疾病，如糖尿病、膀胱癌、帕金森病、多发性硬化，以及如前列腺摘除术或子宫切除术等手术，都有可能损伤排尿反射涉及的神经，最终导致尿失禁。
