Fibrous joints are called “fixed” or “immovable” joints because they do not move. When the connective tissue between the adjacent bones is reduced to a narrow layer, these fibrous joints are now called sutures. Fibrosis Definition Fibrosis is the replacement of normal tissue with scar tissue. In the skull the joints between the bones are called sutures.Such immovable joints are also referred to as synarthroses The membrane is important in creating compartments to separate different structures, distributing the impact of forces and separating the joints. The three types of fibrous joints are sutures, gomphoses, and syndesmoses. Fibrous septa extend from the mediastinum testis, creating the borders of the lobules which contain the seminiferous tubules. Ligaments are fibrous connective tissue that attaches bone to bone, similar to the way tendons attach muscles to bones.
