Total questions: 11
Worksheet time: 6mins
Urine production in the fetus begins approximately at:
6th week of gestation
8th week of gestation
12th week of gestation
D. At birth
Low fetal urine output most commonly results in:
Polyhydramnios
Hydronephrosis
Oligohydramnios
Anuria after birth
Between the 4th and 7th weeks of development, the cloaca divides into
Bladder and urethra
Urogenital sinus and anorectal canal
Mesonephros and metanephros
Allantois and yolk sac
The upper (vesical) part of the primitive urogenital sinus gives rise to the:
Prostatic urethra
Membranous urethra
Urinary bladder
Vestibule
In males, the pelvic part of the urogenital sinus forms:
The prostatic and the membranous urethra
Penile urethra only
Epididymis
Vas deferens
The urogenital system primarily develops from the:
Paraxial mesoderm
Lateral plate mesoderm
Endoderm
Intermediate mesoderm
The pronephros in humans:
Develops into the adult kidney
Is fully functional during fetal life
Is a rudimentary and nonfunctional structure
Persists after birth
The pronephros appears during:
The 3rd week of gestation
The 4th week of gestation
The 8th week of gestation
The 12th week of gestation
The mesonephros:
Forms the definitive kidney
Is nonfunctional and disappears immediately
Functions transiently as an embryonic kidney
Develops from the metanephric blastema
The definitive kidney develops from:
Pronephros only
Mesonephros only
Ureteric bud and metanephric blastema
Allantois and cloaca
The ureteric bud gives rise to the:
Nephrons
Renal pelvis
Ureter
Renal cortex
Calyces
