Flexion

The movement known as flexion occurs during descent and is brought about by the resistance felt by the baby's head against the soft tissues and bones of the mother's pelvis. The resistance brings about a flexion in the baby's head so that the chin meets the chest (Figure 1.3, diagram 2). The smallest diameter of the baby's head presents into the pelvis.
