Specializes in Obstetrics and Gynecology

Sutures + fontanels: The fetal head is made up of five bony plates and two spaces called fontanels. This deign allows for the plates to slide over each other and elongate the head as it squeezes through the vaginal canal. It aids childbirth by making the head momentarily smaller to allow for easier passage.
