Understanding the Four Cardinal Movements of Labor

------------------------------------------------

During labor, a woman's body undergoes several complex physiological changes to facilitate childbirth. One crucial aspect of this process is understanding the four cardinal movements that guide fetal descent and delivery.

The Four Cardinal Movements of Labor

------------------------------

1. Effacement: This refers to the gradual dilation or thinning of the cervix in preparation for birth.

2. Expulsion: This movement involves the actual pushing stage, where both mother's uterine contractions and baby's downward pressure work together to deliver the fetus.

The third cardinal movement is often considered part of expulsion due to its close temporal relationship with it:

3. Extension: During this phase, there is a widening of the pelvic outlet as well as stretching or tearing if necessary to allow for passage of the fetal head or shoulders.

Finally,

4. Expulsion/Excretion

Understanding these movements can help expectant mothers better prepare themselves both physically and emotionally for labor and delivery.
