Crazy placentas!

Here are some crazy looking placentas! You will see some velamentous insertions on these bad boys. In a velamentous cord insertion, the umbilical cord inserts into the fetal membranes (choriamniotic membranes), then travels within the membranes to the placenta (between the amnion and the chorion). The exposed vessels are not protected by Whartons Jelly and hence are vulnerable to rupture.
