ANATOMY

Detailed explanation-1: -The urogenital system arises from intermediate mesoderm which forms a urogenital ridge on either side of the aorta. The urogenital ridge develops into three sets of tubular nephric structures (from head to tail): the pronephros, the mesonephros, and the metanephros.

Detailed explanation-2: -Intermediate mesoderm forms the kidneys, ureters and the vasculature. Splanchnopleuric mesoderm forms the smooth muscle and connective tissue of the bladder. Endoderm forms the bladder and urethra.

Detailed explanation-3: -The urogenital sinus gives rise to development of the lower vagina, vulva, and urethra during embryonic development, and these tissues are estrogen dependent.

Detailed explanation-4: -2.1 Embryology The genital tract is derived from the urogenital ridge, where the testes develop in the dorsal wall of the abdominal cavity. They descend into the scrotum with an evagination of the peritoneum, the tunica vaginalis propria, which forms a serous cavity around the testes.
