THE DELIVERY PROCESS
The delivery process is described in terms of fetal station, lie, attitude, and presentation.
This is the relationship between the presenting part of the baby -- the head, shoulder, buttocks, or feet -- and two parts of the mother's pelvis called the ischial spines. Normally the ischial spines are the narrowest part of the pelvis. They are a natural measuring point for the delivery progress.
