The section passes through the region of the trunk behind the vitelline duct.
vitelline -us: yellow, with a slight tinge of red, like yolk of an egg.
The yolk-sack was large and vascular, and was connected with the fœtal vascular system by a vitelline artery and two veins.
It unites with the common stem of the allantoic and vitelline veins in front of the liver.
The stage of about the greatest development of both the vitelline membrane and zona radiata is represented on Pl.
The only membrane enclosing the individual eggs is the vitelline membrane.
Now, the human ovum or egg consists of a vitellus or yolk, which is covered by a similar membrane, known as the vitelline.
The peripheral segment of the omphalo-mesenteric artery disappears with the cessation of the vitelline circulation.
The portion of the intestine behind the vitelline duct is, as in all the Vertebrata, at first straight.
The primitive hepatic duct is directed cephalad in the mesogastrium between the vitelline duct and the stomach (Fig. 101).
