Answer 1

please mark it as brainlist answer

Fixed joints, also called synarthrosis joints, refer to the joints that provide stability to certain areas of the body, such as the joints of the bones of the skull and pelvis. They are characterized by the continuity of bony segments that are tightly joined and are separated by a thin layer of fibrous connective tissue. Synarthrosis joints are called “fixed” or immovable” because they do not move.

There are three different types of fixed joints in the body: sutures, syndesmoses and gomphoses. Sutures are the junctions between the skull bones. They include:

Plane suture: The edges of the articulating bones are fairly smoothSerrate suture: The most common suture, includes sharp interlocking articulationsLap suture: The edge of one bone overlaps another articulating bone
