cranial sutures

Cranial sutures are flexible joints made of tough connective tissue that connect the bones of the skull. They allow the skull to expand slightly during early life as the brain grows. These sutures gradually ossify and fuse as a person ages, creating solid bone. The main sutures include the coronal, sagittal, lambdoid, and squamosal sutures. Their structure provides both protection for the brain and flexibility during birth and growth, and their pattern can also help in identifying age or certain medical conditions.
