development of the urogenital sinus into the urinary bladder and definitive urogenital sinus describe pictured layout =

Back 14

-Allantois is at the anterior superior
-leads into urinary bladder
-bladder turns inferior making a boomerang shape
-ureter is at the bend
-halfway between bend inferior to the end is the seminal vesicle on posterior wall
-on the anterior side just distal to seminal vesicle is the pelvic part of urogenital sinus
-at the end is the definitive urogenital sinus

-Inferior to the above structure is the anorectal canal

Front 15

male
the definitive urogenital sinus develops into the penile urethra. The prostate gland is formed by buds from the urethra and seminal vesicles are formed by budding from the ductus deferens.
