Anatomical terminology

The internal urethral orifice is the opening of the urinary bladder into the urethra.[1]

Anatomy

It is usually somewhat crescent-shaped.[citation needed]

Relations

It is formed by the neck of the urinary bladder. It opens at the apex/inferior angle of the trigone of the bladder, some 2-3 cm anteromedial to either ureteral orifice.[1]

The mucous membrane immediately posterior to it presents a slight elevation in males - the uvula vesicae - caused by the middle lobe of the prostate.[citation needed]
