What is "fibrous joint"

n. an immovable joint (especially between the bones of the skull) [syn: suture, sutura]

Fibrous joints are connected by dense connective tissue, consisting mainly of collagen. In these joints the bones are firmly interlocked by irregular hacksaw-like edges. These are fixed joints where bones are united by a layer of white fibrous tissue of varying thickness. The joints between the bones are called sutures. Such immovable joints are also referred to as synarthrosis.
