Pressure transmitted from the fundus of the uterus down the fetal spine will force the occiput lower than the sinciput, increasing flexion and resulting in the conversion of the suboccipitofrontal diameter of 10, As the leading part is driven onto the pelvic floor, the resistance of the muscular diaphragm and its gutter shape, sloping downwards anteriorly, cause the occiput to rotate forwards in the pelvis, The occiput escapes from beneath the subpubic arch and the smallest possible diameters, which are the suboccipitobregmatic diameter of 9.5, Restitution is a movement made by the head following delivery which brings it into correct alignment with the shoulders. This concept has been challenged and it is probable that progress rather than an estimated time limit is more useful as an indicator of normality (, h in multiparous women. Third stage of labor: The part of labor from the birth of the baby until the placenta and fetal membranes are delivered.The third stage of labor is also called the placental stage.
