Resolution of physiological umbilical hernia occurs at which week of gestation ?
Correct Answer: 10 weeks
Description: As the amniotic cavity grows it pushes into the chorionic cavity to obliterate it and the fusion of the amnion and chorion takes place.The amnion then surrounds the amniotic cavity except at the region of umbilical ring,where it is reflected onto the connecting stalk and yolk sac.the primitive umbilical cord arises from the connecting stalk and yolk sac together.Proximally the primitive cord contains some loops of intestine and the allantois.This is the physiological omphalocele, which disappears by the end of 3 rd month.
