Deck 11: Urogenital System

Question 1

________ Oligohydramnios

A)Renal agenesis
B)Nephrogenic cord
C)Metanephric diverticulum
D)Kidney lobes
E)Polycystic kidney

Answer 1

A
Oligohydramnios (an abnormally small volume of amniotic fluid)may be associated with renal agenesis (absence of kidneys).In the neonate,renal agenesis is suggested by large,low-set ears.This type of auricle also suggests numerical chromosomal abnormalities .The fetal kidneys normally produce large amounts of urine,which is excreted into the amniotic fluid.When one or both kidneys fail to form or there is urethral obstruction,the volume of amniotic fluid is small because urine production fails to occur or the urine cannot pass into the amniotic fluid.

Question 2

________ Intermediate mesoderm

A)Renal agenesis
B)Nephrogenic cord
C)Metanephric diverticulum
D)Kidney lobes
E)Polycystic kidney

Answer 2

B
The intermediate mesoderm in the early embryo forms a longitudinal mass on each side called the nephrogenic cord.These cords give rise to nephrons,which connect with the collecting tubules formed from the metanephric diverticula.

Question 3

________ Source of nephrons

A)Renal agenesis
B)Nephrogenic cord
C)Metanephric diverticulum
D)Kidney lobes
E)Polycystic kidney

Answer 3

B
The metanephric mesenchyme in the nephrogenic cords gives rise to nephrons.When stimulated by a substance produced by the metanephric diverticulum,the metanephric mesenchyme begins to differentiate into nephrons.
