As the bladder gets full, the detrusor contracts.

当膀胱涨满时，逼尿收缩。

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

这通常是由于不受抑制逼尿随机收缩。

To treat urge incontinence, the focus is on decreasing the detrusor muscle activity.

急迫性尿失禁治疗方法，重点在于减少逼尿活动。

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

无论男性女性，尿道内口逼尿增厚，形成尿道内括。

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

在逼尿里有千万层交织成网感受器，当膀胱尿量增加时会拉这些感受器。

Relaxation techniques to relax the bladder as well as antimuscarinic medications can decrease detrusor muscle contractions.

放松疗法放松膀胱以及抗毒蕈碱药物可减少逼尿收缩。

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，造成逼尿收缩而内扩松弛。

The bladder wall consists of three layers — an inner mucosa, surrounded by a thick muscular layer called the detrusor wrapped in a fibrous, protective outer membrane.

膀胱壁由三层组成——内粘膜，被一层厚厚叫做逼尿肉层包围，这层肉层包裹在纤维状保护性外膜中。

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组织构成，当膀胱注入尿液时，它会像气球一样膨胀扩。

This tells the detrusor to contract while the internal urethral sphincter simultaneously opens, and the external sphincter relaxes so that the pee can flow out.

这告诉逼尿收缩，同时尿道内括打开，外括放松，以便尿液流出。

In addition there is a thick muscular layer called the detrusor muscle that helps with bladder contraction during urination and it has fibrous adventitia outer layer.

此外，还有一层较厚肉层，称为逼尿，能辅助排尿过程，其外层有纤维外膜。

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轻微收缩增加膀胱压力，从而让使人知道膀胱已经满了。

This could be due to a blockage in urine flow, like a hypertrophic prostate in men which presses on the urethra or an ineffective detrusor muscle.

这可能是尿液流动中遭遇阻塞，比如男性前列腺增生压迫尿道，或者是膀胱逼尿失灵。

The bladder is able to expand and contract because it's wrapped in a muscular layer, called the detrusor muscle, and within that, lining the bladder itself is a layer of transitional epithelium containing " umbrella cells" .

膀胱既可以扩也可以收缩，因为膀胱壁有一层肉，叫做逼尿，而且膀胱内衬有一层由“伞状细胞”（盖细胞）组成变移上皮。
