Urethral orifice

Urethral Orifice

The urethral orifice is the external opening or outlet of the urethra, a tube that carries urine from the bladder to the outside of the body. It is an essential part of the urinary system, and its primary function is to allow the passage of urine.

Anatomy

In males, the urethral orifice is located at the tip of the penis, while in females, it is located in the vulva, between the clitoris and the vaginal opening. The female urethral orifice is typically shorter than its male counterpart, which contributes to the higher incidence of urinary tract infections in women.

Physiology

The urethral orifice is typically closed and is opened voluntarily when urine is to be expelled from the body. This is controlled by the internal urethral sphincter and the external urethral sphincter, which are circular muscles that surround the urethra.

Clinical significance

Conditions that can affect the urethral orifice include urethritis, urethral stricture, and urethral prolapse. Symptoms of these conditions can include pain, difficulty urinating, and blood in the urine. Treatment can involve medication, surgery, or other interventions, depending on the specific condition and its severity.
