The trigone is a smooth triangular region of the internal urinary bladder formed by the two ureteral 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. The signals become stronger as the bladder continues to fill.
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 isendodermal). In the female the mesonephric ducts regresses, causing the trigone to be less prominent, but still present.

What is the area of posterior bladder wall free of rugae?
The area of the posterior bladder wall that is free of rugae is called the trigone. The trigone is a smooth triangular region in the bladder formed by the two ureteral orifices and the internal urethral orifice. It is a common site for bladder cancer to develop due to its smooth nature.
Rugae are folds in the bladder that allow for expansion However the floor of the bladder does not have rugae and does not expand This triangular area is called the trigone?
The trigone is a triangular area in the bladder where the ureters and urethra connect. It is located in the base of the bladder and is made up of smooth muscle that does not expand like the rest of the bladder. The trigone helps maintain the shape and support the function of the bladder.
