Final answer:

The locations of the ProNephros, MesoNephros, and MetaNephros are reversed; they represent different stages of kidney development with the metanephros being the final stage leading to the adult kidney.

Step-by-step explanation:

The statement "ProNephros appear in the Cervical region. MesoNephros appear in the ThoracoLumbar region. MetaNephros appears in the Sacral region" is False; their locations are reversed. During the development of the kidneys in embryogenesis, these structures represent different stages of kidney development. The pronephros is the most anterior, followed by the mesonephros, and finally the metanephros, which develops into the adult kidneys. The pronephros is temporary and nonfunctional in humans, while both the mesonephros and metanephros have functions during development. The metanephros is the last to develop and is located in the pelvic region, which will become the permanent kidney.
