Q

Cardinal Movements
* What are the steps

__1__ is presenting part at “zero” station.

__2__ is brought about by the force of uterine contractions and maternal valsalva efforts.

__3__ is baby’s chin moves to its chest thus changing the presenting part from occipitofrontal to the smaller suboccipitobregmatic.

__4__ occurs usually at the ischial spines and the fetal head enters pelvis in transverse diameter, rotates so the occiput turns anteriorly or posteriorly toward the pubic symphysis.

__5__ occurs when largest diameter of the fetal head is encircled by the vaginal introitus and station is +5.
