|type="()"}
- &nbsp; extends from the primitive node to the parachordal plate
+
- &nbsp; placenta accreta
- &nbsp; is a primary inducer during organogenesis
+
|| Correct! About 75-78% of cases with an abnormal adherence, with absence of decidua basalis. The incidence of placenta accreta also significantly increases in women with previous cesarean section compared to those without a prior surgical delivery.
+ &nbsp; is a site of migration of epiblast cells to form the mesoderm
+
- &nbsp; placenta increta
|| The primitive streak is a site of migration of epiblast cells to form firstly endoderm and then the mesoderm.
+
|| Incorrect! About 17% of cases when the placenta attaches deep into the uterine wall and penetrates into the uterine muscle, but does not penetrate the uterine serosa. Placenta increta accounts for approximately 15-17% of all cases.
- &nbsp; persists as the parachordal plate
+
+ &nbsp; placenta percreta
- &nbsp; all of the above are correct
+
|| Incorrect! About 5% of cases with placental villi penetrate myometrium and through to uterine serosa.
 +
- &nbsp; vasa previa
 +
|| Incorrect! {{Vasa previa}} (vasa praevia) placental abnormality where the fetal vessels lie within the membranes close to or crossing the inner cervical os (opening) and generally diagnosed (98%) by {{ultrasound}}.
