The part of the urethra that is located within the urogenital diaphragm is known as the membranous urethra. This section is found between the prostatic urethra and the spongy urethra, and it is relatively short compared to other parts of the urethra.
The membranous urethra is surrounded by the external urethral sphincter, which plays a crucial role in controlling the flow of urine. This part of the urethra is important for both urinary control and sexual function. Since it passes through the urogenital diaphragm, it is also associated with the pelvic floor muscles, which provide additional support and control.
Understanding the anatomy of the urethra, including the membranous section, is vital for recognizing how urinary incontinence and other urological conditions can occur, as well as how surgical procedures affecting this area might be approached.
