The skull bones are connected by fibrous joints.

A suture is a type of fibrous joint which only occurs in the skull (or "cranium").

Fibrous joints are connected by dense connective tissue, consisting mainly of collagen.

It is characterized by premature closure of the fibrous joints between certain bones of the skull in a process known as craniosynostosis.

Most synarthrosis joints are fibrous joints (e.g., skull sutures).

Among babies born with Apert syndrome, the fibrous joints between bones of the skull (sutures) close prematurely (craniosynostosis).

Unlike other fibrous joints, syndesmoses are moveable (amphiarthrodial), albeit not to such degree as synovial joints.

Some cephalic disorders occur when the cranial sutures (the fibrous joints that connect the bones of the skull) join prematurely.

For example, the disorder is typically associated with premature closure of the fibrous joints (cranial sutures) between particular bones of the skull (craniosynostosis).

Sutures are fibrous joints made of a thin layer of dense fibrous connective tissue that unites skull bones.

In addition, the head may have an unusual shape due to premature closure of the fibrous joints (sutures) between certain bones in the skull (coronal synostosis).

In infants with Baller-Gerold Syndrome, there is premature fusion of the fibrous joints (cranial sutures) between certain bones in the skull (craniosynostosis).

However, in many cases, there is early closure of the fibrous joints (cranial sutures) between certain bones of the skull (craniosynostosis), resulting in an abnormally shaped head.

Structural and functional differences distinguish synovial joints from cartilaginous joints (synchondroses and symphyses) and fibrous joints (sutures, gomphoses, and syndesmoses).

The main structural differences between synovial and fibrous joints are the existence of capsules surrounding the articulating surfaces of a synovial joint and the presence of lubricating synovial fluid within those capsules (synovial cavities).
