Sexual reproduction is a source of genetic variations . There are three types of immovable joints: sutures, syndesmosis, and gomphosis. The joints in the skeleton keep it all together. Sharpey's fibers, a network of connective fibres that develop from each bone into the adjacent one, hold sutures together. A prominent example of a fixed joint is the skull, which is made up of a number of fused bones. There are three main types of joints such as Fibrous (immovable), Cartilaginous (partially moveable) and Synovial (freely moveable) joint. The immovable joint allows for greater mobility in the non-ossified tissues surrounding it. The immovable joint is very important because it allows for large movements of the head within the cervical spine while maintaining stability. It fits into a cup-like depression of the other bone. Bones at these joints have no joint cavity and are held together structurally by thick fibrous connective tissue, usually collagen. It is also referred to as synarthrotic (meaning immovable). Examples- articulations of bony sockets, skull sutures, and teeth in the facial skeleton. There is a thick connective tissue present in the articulations of fibrous joints which leads to a maximum of them in an immovable condition but there are some types of fibrous joints that are movable.Below given are examples of three.
