The cervix is a band that protects against fetal loss. Located in the lower uterus, it is thick and fibrous, and along with mucous glands, helps create a protected and sterile environment for fetal development. An insufficient or weakened cervix dilates and thins before term; it is unable to bear the weight of the growing fetus without medical intervention.
