membranous urethra

Monday 14 March 2022


Definition : A small (1 or 2 cm) portion passing through the external urethral sphincter. This is the narrowest part of the urethra. It is located in the deep perineal pouch.

The membranous urethra or intermediate part of male urethra is the shortest, least dilatable, and, with the exception of the urinary meatus, the narrowest part of the urethra.

The bulbourethral glands ( Cowper glands ) are found posterior to this region but open in the spongy urethra.
