What is another word for bladder sphincter?
Pronunciation: [blˈadə sfˈɪŋktə] (IPA) 
The bladder sphincter, also known as the urethral sphincter, is a muscle that controls the flow of urine from the bladder. There are several synonyms for this muscle, including the urinary sphincter, the vesical sphincter, and the prostatic sphincter. The urethral sphincter can be further subcategorized into the external urethral sphincter, located at the base of the bladder, and the internal urethral sphincter, located closer to the bladder neck. The purpose of the bladder sphincter is to allow for conscious control over urination, while also preventing involuntary leakage. Any dysfunction of this muscle can result in urinary incontinence or retention, making it an important anatomical structure to understand.
