Begins as a continuation of the bladder neck and passes through the prostate gland. Once the bladder becomes full urine flows through the urethra and leaves the body at the urethral meatus which is located at tip of the. Summary and Blood Supply The bulbar and penile urethra fossa navicularis and urethral meatus together represent what is called the anterior urethra.
Functionally the urethras role is fairly simple in that it allows for transport of urine and semen from the bladder and ejaculatory ducts through the penis. The urethra is surrounded by the corpus spongiosum one of the cylindrical spaces of soft tissue of the penis described earlier. The membranous urethra is the shortest and narrowest part of the male urethra.
The male urethra connects the urinary bladder to the penis. The male urethra is a narrow fibromuscular tube that conducts urine and semen from the bladder and ejaculatory ducts respectively to the exterior of the body see the image below. Male urethra It is 18-20 cm in length Extends from internal urethral orifice in bladder to external urethral orifice meatus at the tip of glans penis 6.

The male urethra is a pelvic urinary organ that functions primarily as a connecting cord which transports urine from the urinary bladder to the exterior.
It commences at the internal urethral orifice in the trigone of the bladder and opens in the navicular fossa of the glans penis at the external urethral meatus which is the narrowest part of the urethra. This is typically the widest part of the urethra which then connects to the membranous urethra found in the urogenital diaphragm. The anterior urethra is generally 18-25 cm 9-10 inches long and the posterior urethra is approximately 3-6 cm 1-2 inches long.
Because of vastly different anatomy between the sexes male and female urethras are discussed separately. Preprostatic intramural urethra which extends from the internal urethral orifice to the prostate Prostatic urethra penetrates the prostate in which it is joined by the ejaculatory duct of the male reproductive system. The male urethra measures on average 18-20 cm in length.
The external urethral sphincter muscle is located in the urogenital diaphragm as for the female urethra. IT IS BROADLY DIVIDED INTO THREE PARTS PROSTATIC MEMBRANOUS SPONGY OR PENILE PROSTATIC AND MEMBRANOUS TOGETHER FORM POSTERIOR URETHRA SPONGY PORTION FORMS ANTERIOR URETHRA. 05 - 075 inches 12 - 19 mm in length and is the section of the urethra that passes through the male urogenital diaphragm.
