What does trigone of bladder mean?
The trigone is the neck of the bladder. It’s a triangular piece of tissue located in the lower part of your bladder. It’s near the opening of your urethra, the duct that carries urine from your bladder outside of your body. When this area becomes inflamed, it’s known as trigonitis.
Why is the trigone of bladder important?
Trigone. The trigone is a triangular muscular structure located between the bladder and urethra. Effective connection between the ureters and the trigone are vital for proper functioning of the ureteral valve mechanism.
What is a trigone tumor?
Early infiltrating carcinoma of the trigone is a highly malignant disease. Metastases may be expected in 50 per cent of the cases within one year. The obstructing tumor is attended by infection and renal insufficiency of sufficient degree to result in death in the majority of cases.
What is a trigone in anatomy?
Medical Definition of trigone : a triangular body part specifically : a smooth triangular area on the inner surface of the bladder limited by the apertures of the ureters and urethra.
What 3 openings form the trigone?
In the bladder base is a triangular area: the trigone. The trigone has a flattened appearance with a smooth epithelial covering. The corners of the trigone are formed by three orifices: the paired ureteral orifices and the internal urethral orifice.
What is the function of the trigone?
The trigone (a.k.a. vesical trigone) is a smooth triangular region of the internal urinary bladder formed by the two ureteric orifices and the internal urethral orifice. The area is very sensitive to expansion and once stretched to a certain degree, the urinary bladder signals the brain of its need to empty.
Where does trigone of the bladder come from?
Purpose. In the classic view of bladder development, the trigone originates from the mesoderm-derived Wolffian ducts while the remainder of the bladder originates from the endoderm-derived urogenital sinus.
What contains the trigone?
What is the trigone area of the bladder?
The trigone is a triangular portion of the bladder floor bordered (ventrally) by the internal urethral opening or bladder neck and (dorsolaterally) by the orifices of the right ureter and left ureter.
Where is the trigone in the bladder?
Is trigone part of kidney?
Where is the trigone located in the human body?
[edit on Wikidata] The trigone (a.k.a. vesical trigone) is a smooth triangular region of the internal urinary bladder formed by the two ureteric orifices and the internal urethral orifice. The area is very sensitive to expansion and once stretched to a certain degree, the urinary bladder signals the brain of its need to empty.
Where does the trigone of the bladder come from?
Embryologically, the trigone of the bladder is derived from the caudal end of mesonephric ducts, which is of mesodermal origin (the rest of the bladder is endodermal).
How are kidney stones removed from the urinary tract?
Stones that do not pass on their own are removed with lithotripsy (the use of shock waves to break up those stones) or an endoscopic technique (the use of specialized tools to view and operate on internal organs). Urinary tract stones begin to form in a kidney and may enlarge in a ureter or the bladder.
How are bladder stones related to kidney stones?
The stones are also called bladder calculi. Stones can form in any of the organs that make up the urinary system. Bladder stones form in the bladder, which holds urine. Bladder stones may be related to stones that have formed in other parts of the urinary tract, such as the kidneys.
