            • Definitions

              • Marginal placental cord insertion (MPCI): Umbilical cord (UC) inserts near placenta margin
                • All branching vessels within placenta, typically tightly coiled
                  • No submembranous vessels
              • Velamentous cord insertion (VCI): UC inserts on membranes and vessels are unprotected by Wharton jelly 
                • Submembranous vessels branch and travel to placenta, typically loosely coiled
              • Furcate cord insertion is subset: UC vessels branch before insertion on placenta or adjacent membranes
