The fetal chin flexes toward the chest describes which movement?

• A. Flexion
• B. Engagement
• C. Descent
• D. Internal rotation

Answer: (A)

In labor, the fetus’ head typically flexes so the chin comes toward the chest. This flexion brings the smallest presenting diameter of the head to the maternal pelvis, helping the head navigate through the birth canal and align for birth. If the chin stayed away from the chest (head extended), a larger presenting diameter would be encountered, which can slow progress. Engagement refers to the head entering the pelvis, descent is the downward movement through the pelvis, and internal rotation is the turning of the head to align with the birth canal for delivery.
