Normal presentation

The vertex presentation is a normal presenting part of the fetus which arrives first at the mother's pelvic brim. In about, 95% of deliveries are vertex presentations. In vertex presentation, the baby's chin is pushed down towards its chest so that the vertex (occiput) is the leading part entering the mother's pelvis (Figure 4.4. below). The baby's head is said to be "well-flexed" in this position and the fetus delivered safely.
