How Do You Spell SPHINCTER VESICAE?

1. Sphincter vesicae, also known as the urinary bladder sphincter or the bladder neck sphincter, refers to a circular muscle that surrounds the neck of the urinary bladder and functions to regulate the flow of urine from the bladder into the urethra.

   The sphincter vesicae is situated at the base of the bladder, where the bladder connects to the urethra. It consists of smooth muscle fibers arranged in a circular pattern, forming a ring-like structure. This muscle is under voluntary control, meaning it can be consciously contracted or relaxed to allow or prevent the release of urine.

   When the sphincter vesicae is contracted or tightened, it prevents the flow of urine from the bladder into the urethra. This is essential for maintaining continence, allowing individuals to control the timing and release of urine. Conversely, when the sphincter vesicae is relaxed or loosened, it opens up the passage between the bladder and urethra, enabling urine to flow out during the act of urination.

   Disorders or dysfunction of the sphincter vesicae can lead to urinary incontinence or retention. In cases of urinary incontinence, the sphincter may be weakened or unable to effectively hold urine, causing involuntary leakage. On the other hand, urinary retention occurs when the sphincter fails to relax, impairing the ability to empty the bladder completely.

   In summary, the sphincter vesicae is a crucial muscle responsible for controlling the release of urine from the bladder, ensuring normal urination and maintaining urinary continence.
