one of the remains of the membranous skeleton that unite the bones of the skull in a newborn infant. The fontanels enable the head of the fetus to be compressed as it passes through the birth canal. The anterior fontanel—the junction of the frontal and temporal bones—closes in the second year of life. The posterior fontanel, which is located at the site where the occipital and temporal bones join, closes before or shortly after birth, as do the mastoid and sphenoidal fontanels. Delayed closing of the fontanels is observed in rickets and a number of other diseases.
