3-5. MALE URETHRA
The male urethra (see figure 3-5) is a tube about 20 cm (8 inches) in length that forms an S curve. It is the terminal portion of both the urinary and reproductive tracts. The male urethra has three divisions: the prostatic urethra, which passes through the prostate gland, the membranous urethra, which contains the external sphincter of the bladder, and the remainder, called the bulbous urethra. The male urethra is composed of mucous membrane that is continuous with that of the bladder and merges with the submucous tissue, which in turn connects the urethra with other structures that it traverses.
