The sutures of the skull, also referred to as the cranial sutures, are fibrous joints that connect the bones of the skull. They appear as intricate thin lines that mark the adherence between the bones and the growth and closure of the cranial fontanelles.

The dense fibrous tissue that connects the sutures is made mostly out of collagen. These joints are fixed, immovable, and they have no cavity. They are also referred to as the synarthroses. In fetal skull, the sutures are wide and allow slight movement during birth, but later in life they become rigid and fixed.

This article will explain the anatomy, structure and function of the sutures of the skull.
