This is typically due to an uninhibited detrusor muscle that contracts randomly.

In men and women, around the internal urethral orifice, the detrusor muscle thickens to form the internal sphincter.

无论男性女性，尿道内口的逼尿肌增厚，形成尿道内括约肌。

Inside the layers of detrusor muscles are millions of stretch receptors that get triggered as the bladder fills.

在逼尿肌里有千万层交织成网的牵张感受器，当膀胱尿量增加时会牵拉这些感受器。

And it causes an increase in parasympathetic stimulation and decrease in sympathetic stimulation which makes the detrusor muscle contract and the internal sphincter relax.

脊髓反射导致副交感神经兴奋，而交感神经兴奋受到抑制，造成逼尿肌收缩而内扩约肌松弛。

This organ's muscular wall is made of tissue called detrusor muscle which relaxes as the bladder fills allowing it to inflate like a balloon.

这个器官壁是由一种叫做逼尿肌的组织构成的，当膀胱注入尿液时，它会像气球一样膨胀扩张。

A reflex signal travels back to your bladder, making the detrusor muscle contract slightly and increasing the bladder's pressure so you're aware that it's filling up.

一个反射信号再反射到膀胱使括约肌轻微收缩增加膀胱的压力，从而让使人知道膀胱已经满了。
