What is the Urethra? The urethra is a thin, fibromuscular tube that begins at the lower opening of the bladder and extends through the pelvic and urogenital diaphragms to the outside of the body, called the external urethral orifice. The urethra also connects the to the ductus deferens in males, for the ejaculation of sperm. There is a sphincter at the upper end of the urethra, which serves to close the passage and keep the urine inside the bladder. As the passage needs to traverse the length of the penis, it is significantly longer in males than females.

Urethritis (Urethra Infection) in Men and Women Urethritis is the medical term for inflammation of the urethra, the muscular tube that carries urine from the bladder to pass it out into the external environment. Due to the frequency of urethritis occurring as a result of an infection, it is often accepted that the term urethritis is due to infection-induced inflammation of the urethra. However there are non-infectious causes of urethritis, although this is rare in comparison to infectious factors.

Urethra The first part, next to the urinary bladder, passes through the prostate gland and is called the prostatic urethra. The second part, a short region that penetrates the pelvic floor and enters the penis, is called the membranous urethra. The third part, the spongy urethra, is the longest region.This portion of the urethra extends the entire length of the penis, and the external urethral orifice opens to the outside at the tip of the penis.he final passageway for the flow of urine is the urethra, a thin-walled tube that conveys urine from the floor of the urinary bladder to the outside. The opening to the outside is the external urethral orifice. The mucosal lining of the urethra is transitional epithelium.

- The urethra in males is the tube that carries urine from the bladder to the outside of the body and also serves as the channel though which semen is ejaculated. The anterior urethra is the portion of the urethra from the tip of the penis to just before the prostate.he scar (stricture) is composed of dense collagen and fibroblasts (proteins that form cell-producing connective tissue) and thus contracts in all directions, shortening urethral length and narrowing the diameter of the urethra. Strictures usually do not cause symptoms until the urethra tube is below a certain size.
