The trigone of the bladder is formed by the openings of which structures?

The trigone is the smooth, triangular area on the bladder floor that is bounded by three openings: the two ureteric orifices at the back and the internal urethral orifice at the front. So it’s formed by the openings of the ureters and the urethra. The renal pelvis and other structures don’t create these boundaries, and the apex is not an opening that defines the trigone.
