TRIGONE Meaning and
Definition
-
Trigone, in human anatomy, refers to a triangular region or structure found in various parts of the body. However, the term is most commonly used to describe a specific area within the urinary bladder. The trigone is located near the base of the bladder, bordered by the ureter openings and the internal urethral orifice, creating a triangle-shaped region.
In the urinary bladder, the trigone is covered by smooth, non-glandular mucous membrane. It is known for its unique properties, such as relatively immobility and a resistance to stretching. The trigone plays an important role in maintaining proper urinary function. Its function includes acting as a funnel to direct urine flow from the ureters to the urethra and preventing reflux of urine back into the kidneys. The smooth nature of the trigone helps facilitate the passage of urine and minimize friction during its movement.
Pathological conditions or abnormalities in the trigone can lead to urinary problems and various diseases, such as urinary tract infections and bladder dysfunction. Medical professionals may assess the condition of the trigone using techniques like cystoscopy, which involves inserting a thin tube with a camera into the bladder to visualize the structure.
Overall, the trigone is a critical anatomical structure in the bladder, ensuring efficient and proper urinary function.
