Internal opening of the urethra

The urethral orifice (internal) is an opening that is located on the inner wall of the urethra and serves to drain urine from the bladder. It is located at a level of 1-2 centimeters from the entrance to the bladder and has the shape of a funnel.

The urethral meatus is one of two openings through which urine passes from the bladder into the urethra. The second opening is the external urethral opening, which is located on the anterior wall of the urethra.

The internal opening of the urethra has several functions. First, it helps control the volume of urine excreted. When the bladder is full, the internal opening opens and urine begins to flow out of the bladder through the urethra. Secondly, the internal opening of the urethra helps protect the bladder from infections. When urine enters the bladder, it passes through the opening of the urethra and enters the urethra, where further filtration and cleansing of bacteria and other impurities occurs.

In addition, the internal opening of the urethra plays an important role in sexual function. During sexual intercourse, when a man or woman reaches orgasm, the inner wall of the urethra contracts and closes the opening, which helps prevent semen or urine from flowing from the urethra into the genitals.

However, if the internal opening of the urethra is damaged or blocked, it can lead to serious health problems such as urinary incontinence or urinary tract infections. Therefore, it is important to monitor the health of the internal opening of the urethra and, if necessary, consult a doctor.

The internal urethral opening is a small opening in the wall of the anterior wall of the urethra, located in the lower part of the bladder. The hole has a round shape and is located at a distance of approximately 1.5-2 cm from its bottom. Inside this opening is the mucous membrane of the bladder, which forms the mucous membrane of the urethra and nourishes the glands that secrete secretions to create a lubricating protective fluid in the canal. The opening of the urethra is in close connection with both the bladder and the prostate gland.
