The fusion of this suture causes a certain change in the shape of the skull; a deformity of the skull. [ 7 ] Virchow's law dictates that, when premature suture closure occurs, growth of the skull typically is restricted perpendicularly to the fused suture and enhanced in a plane parallel to it, thus trying to provide space for the fast-growing ...
If the suture is not present at birth because both frontal bones have fused (craniosynostosis), it will cause a keel-shaped deformity of the skull called trigonocephaly. Its presence in a fetal skull, along with other cranial sutures and fontanelles , provides a malleability to the skull that can facilitate movement of the head through the ...
If certain bones of the skull grow too fast then premature fusion of the sutures, craniosynostosis, may occur. [1] This can result in skull deformities. [1] These deformities include: [3] Brachycephaly (both sides) Plagiocephaly (one side only) Oxycephaly (both sides)

Side view of the skull Human skull side sutures right. A suture is a type of fibrous joint that is only found in the skull (cranial suture). The bones are bound together by Sharpey's fibres. A tiny amount of movement is permitted at sutures, which contributes to the compliance and elasticity of the skull. These joints are synarthroses. [1]
The sagittal suture, also known as the interparietal suture and the sutura interparietalis, [citation needed] is a dense, fibrous connective tissue joint between the two parietal bones of the skull. The term is derived from the Latin word sagitta , meaning arrow .
Increased cranial pressure in infants may cause the fontanelles to bulge or the head to begin to enlarge abnormally. [7] It can occur due to: [4] Craniosynostosis – premature fusion of the cranial sutures [8] Encephalitis – swelling (inflammation) of the brain, most often due to infections; Hydrocephalus – a buildup of fluid inside the skull
The sphenofrontal suture is the cranial suture between the sphenoid bone and the frontal bone. Additional images. The skull from the side.
