The fontanelle allows the skull to deform during birth to ease its passage through the birth canal and for expansion of the brain after birth. While the posterior and lateral fontanelles are obliterated by about six months after birth, the anterior is not completely closed until about the middle of the second year. Full ossification starts in the late twenties and finishes before the age of 50 . [WP,unvetted]. MA:0002830 bregmatic fontanelle FMA:75439
