connecting stalk मीनिंग इन हिंदी

Progressive expansion of the amnion from the umbilical ring ( surrounding the roots of the vitelline duct and connecting stalk ) creates a tube of amniotic membrane.
The lateral body wall folds, pulling the amnion in with it so that the amnion surrounds the embryo and extends over the connecting stalk, which becomes the umbilical cord, which connects the fetus with the placenta.
