Rhabdosphincter

The Rhabdosphincter, also known as the striated urethral sphincter, is a muscle of the urethra that helps control the release of urine from the body. It is a part of the urinary system and plays a crucial role in urinary continence.

Anatomy

The rhabdosphincter is a circular band of striated muscle located in the pelvis. It surrounds the membranous urethra and is found in both males and females. In males, it is located just below the prostate gland, while in females, it is found below the bladder and above the vaginal opening.

Function

The primary function of the rhabdosphincter is to control the flow of urine from the bladder through the urethra and out of the body. It does this by contracting to close off the urethra, preventing urine from passing. When it is time to urinate, the rhabdosphincter relaxes, allowing urine to flow out.

Clinical significance

Damage or dysfunction of the rhabdosphincter can lead to urinary incontinence. This can occur as a result of aging, childbirth, or surgical procedures such as a prostatectomy. In such cases, treatments may include pelvic floor exercises, medication, or surgery.
