fontanelle A soft place in the scalp over a gap between four bones of the skull (the frontal and parietal bones on each side) which is normally present in the newborn infant. It gradually closes during the first 12–18 months of life, as bone formation extends until the edges come together at the sutures. The fontanelle reveals changes in pressure inside the skull: it tends to bulge when the baby cries, and to become sunken in a state of dehydration. The pulsations of the underlying brain with the heart beat can be felt at this site through the scalp.
