Mesonephros (cervical region), Pronephros (abdominal region), Metanephros (pelvic region)
QuestionChoice
This is the correct answer. In the fourth week of gestation, the pronephros appear in the cervical region of the embryo. It is non-functional and regresses completely by the end of that week, leading to the development of the mesonephros which functions as the primitive excretory system. Ureteric buds develop from the mesonephric ducts, which are a remnant of the pronephric duct, and this induces the development of the definitive kidney known as the metanephros. The metanephric system is composed of the excretory and collecting system and its development is initiated in the pelvis before the kidneys ascend into the abdomen. As such, the corresponding anatomical regions for the mesonephros and metanephros are the abdominal region and pelvic region respectively.
