Ureteral orifice
Trigone of urinary bladder
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.
Pathology
Clinically important because infections (trigonitis) tend to persist in this region.Additional images
