DETRUSOR Meaning and
Definition
-
The term "detrusor" refers to a muscular layer that forms a part of the urinary bladder wall. Specifically, it is a smooth muscle located within the detrusor muscle layer, which is responsible for the contraction and relaxation of the bladder during the process of urination. The detrusor muscle is the main muscle involved in controlling the voiding of urine from the bladder into the urethra.
The detrusor muscle acts in response to signals from the nervous system, which regulate the filling and emptying of the bladder. When the bladder is filling with urine, the detrusor muscle remains relaxed to accommodate the increasing volume. However, when the bladder reaches a certain level of distension or when the individual desires to urinate, the detrusor muscle contracts, exerting pressure on the bladder and facilitating the expulsion of urine. This contraction is coordinated with the relaxation of the urinary sphincters, allowing smooth and efficient voiding.
Dysfunction or abnormality in the detrusor muscle can lead to various urinary disorders, such as overactive bladder or urinary retention. Overactive bladder occurs when the detrusor muscle contracts involuntarily, causing frequent and urgent urination. On the other hand, urinary retention results from inadequate or insufficient contraction of the detrusor muscle, leading to difficulties in emptying the bladder completely. Proper functioning of the detrusor muscle ensures normal urinary function and plays a vital role in maintaining bladder control.
