What is another name for skull sutures?
The cranial sutures are fibrous joints, also known as synarthroses.
What is the area where two or more bones join together?
The immovable joints between the cranial bones are called sutures.
What cranial bone is not sutured?
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.
What cranial bone articulates with all other cranial bones?
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
What causes Craniosynostosis?
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.

Where is the area where cranial bones join together?
Cranial bones join at sutures.
Articulations between cranial bones are?
sutures

What is the area where two or more bones join together?
The immovable joints between the cranial bones are called sutures.
Is the cranium solid at birth?
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
What is a immovoble joint?
A type of joint that is immovable is called a synarthrotic joint. An example would be the sutures between the cranial bones.
Must a joint allow movement between two bones to be called a joint?
No, some joints, such as the cranial sutures, are immovable.
What is the joint between the jaw and the skull?
the cranial fibrous, cartilaginous, and synovial joints.immovable joints
What kind of joint is a cranial suture both structurally and functionally?
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.

What are two names for the small bones that are trapped within a suture?
Wormian or sutural bones are located in sutures between certain cranial bones.
