Preferred Label : metanephros;
Uberon definition : In mammals, the metanephros is the excretory organ of the fetus, which develops into
the mature kidney and is formed from the rear portion of the nephrogenic cord. The
metanephros is an endocrine and metabolic organ that filters the blood and excretes
the end products of body metabolism in the form of urine[GO];
Uberon synonym : metanephron;
Uberon related term : definite kidney; definitive kidney; metanephric kidney; hind kidney;
Uberon Development note : During the fifth week of gestation, the mesonephric duct develops an outpouching,
the ureteric bud, near its attachment to the cloaca. This bud, also called the metanephrogenic
diverticulum, grows posteriorly and towards the head of the embryo. The elongated
stalk of the ureteric bud, the metanephric duct, later forms the ureter. As the cranial
end of the bud extends into the intermediate mesoderm, it undergoes a series of branchings
to form the collecting duct system of the kidney. It also forms the major and minor
calyces and the renal pelvis;
Uberon Homology note : The ureteric diverticulum grows dorsally into the posterior region of the nephric
ridge. Here it enlarges and stimulates the growth of metanephric tubules that come
to make up the metanephric kidney. The metanephros becomes the adult kidney of amniotes.[well
