Fontanelle is the name for the soft tissue "spaces" between the bones of the skull in babies and infants under the age of two. These areas of soft tissue (although actually strong and tough) enable the infant skull to more easily pass through the birth canal since they allow the bony skull plates to move and reshape slightly as needed during the birth process. These are also commonly called "soft spots" in babies. These areas ossifyto become bone tissue around the childhood age of two, and then gradually over a person's life connect more and more tightly with the adjoining skull plates, forming the cohesive skull. They would then be called "sutures" of the skull instead of fontanelles. The sutures continue to "knit" or heal together with each other throughout a persons life until after the age of 50 when they are usually fully knit. However, in some people some of the sutures, especially the parietal, never do become totally knit. This understanding of the closing process of the fontanelles and knitting of the sutures is helpful in the sciences of forensics and archeology to determine the age at death when skeletons are scientifically studied post mortem.
