Practice Question
During childbirth, the fetus exerts pressure on the maternal tissues. Which of the following structures is most affected by fetal pressure during vaginal delivery?
Answer Choices:
Correct Answer:
Cervix
Rationale:
◼️The cervix is the structure most affected by fetal pressure during vaginal delivery as it must efface (thin) and dilate (open) to allow passage of the fetus.
◼️Hormones such as prostaglandins and oxytocin soften and relax the cervical tissue, facilitating its dilation.
◼️Pressure from the fetal head stimulates further release of oxytocin, creating a positive feedback loop that strengthens uterine contractions.
◼️The progressive mechanical stretching and thinning of the cervix marks the transition through the stages of labor.
◼️This cervical change is the key determinant of labor progress and readiness for delivery.
