There are 2 mechanisms possible during the delivery of the placenta. If the shiny portion comes out first, it is called the Schultze mechanism; while if the meaty portion comes out first, it is called the Duncan mechanism.

Option A: Developed by a mother who needed to express her milk over a long period of time for medical reasons, the Marmet technique mimics the actions of a breastfeeding baby and is the most recommended method of expressing breastmilk by hand.

Option B: Ritgen’s maneuver means that the fetal chin is reached between the anus and the coccyx and pulled anteriorly while using the fingers of the other hand on the fetal occiput to control the speed of delivery and keep flexion of the fetal neck.

Option C: Duncan’s mechanism is the expulsion of the placenta with the presentation of the maternal rough side first, rather than the usual fetal side of the placenta.
