Show answerHide answer
Answer: D · Internal rotation of the shoulders
After the head is born it first untwists (restitution) and then turns further as the shoulders rotate inside the pelvis to the anteroposterior diameter of the outlet. This movement of the head is called external rotation. The anterior shoulder is then born under the symphysis. Watching it tells the midwife which way to guide the shoulders.
- A: Vertex presentations have no breech descent.
- B: Placental separation is part of the third stage.
- C: Extension is how the head is born, before restitution.
