The cranial sutures are band if tissue that are not fused together when babies are born. The cranial sutures fuse completely together around the age of 2.
The closure is complete by about the 3rd month of an infant's life. But sutures continue to grow "closer" and "stronger" until well beyond the teen years.
Approximately 16-18 months of age they close
The cranial sutures are fibrous joints, also known as synarthroses.
The immovable joints between the cranial bones are called sutures.
All cranial bones are joined by sutures with some bones having Sharpey's fibres giving a degree of flexability to some joints but even these joints are still sutures. The part of the skull that is not sutured is the mandible (the jaw) but then this structure is not actually a part of the cranium. The cranium is the portion of the skull that contains the brain.
The Sphenoid (Sphenoidal Bone) this is why it is know as the keystone of the cranial floor *The sphenoid is not a facial bone, it is a cranial bone. There is no facial bone which 'articulates' with 'every other facial bone'. Articulation suggests jointed so sutures would make more sense & these sutures would be on all facial bones edges which knit them together
Craniosynostosis, is a medical condition in which some or all of the sutures in the skull of an infant or child close too early, causing problems with normal brain and skull growth. It can result in craniostenosis, which is the skull deformity caused by the premature closure of the cranial sutures. Also intracranial pressure can be increased. se too early, causing problems with normal brain and skull growth.

The cranial sutures are fibrous joints, also known as synarthroses.
The immovable joints between the cranial bones are called sutures.
The cranium is not solid in a sense that the bones are fusing together. There are eight crainal bones that surround and protect the brain. The bones fuse together at joints known as sutures. When the sutures are completely fused together the skull is solid
A type of joint that is immovable is called a synarthrotic joint. An example would be the sutures between the cranial bones.
No, some joints, such as the cranial sutures, are immovable.

Sutures are a type of fibrous joint that only occur between bones of the skull, or cranial bones and allow only tiny amounts of movement. The bone edges interlock and the gaps are filled with tissue fibres (hence the name fibrous joints). During middle age, the tissue fibres ossify (become bones) so that the skull bones fuse into one single unit. The immovable nature of sutures helps protect the brain, as any movement of the cranial bones would damage the brain. But to answer the actual question that is asked, it is a synarthroses.

Wormian or sutural bones are located in sutures between certain cranial bones.
