Verified step by step guidance

1. Understand the definition of fibrous joints: Fibrous joints are connections between bones where the bones are held together by dense connective tissue, and they typically allow little to no movement.
2. Learn about sutures: Sutures are immovable fibrous joints found between the bones of the skull. They are held together by dense connective tissue and are designed for stability rather than movement.
3. Learn about gomphoses: Gomphoses are specialized fibrous joints that anchor teeth into their sockets in the maxilla or mandible. These joints are immovable and provide stability for the teeth.
4. Learn about syndesmoses: Syndesmoses are fibrous joints where bones are connected by ligaments or interosseous membranes, such as the connection between the tibia and fibula. These joints allow limited movement.
5. Conclude the commonality: Sutures, gomphoses, and syndesmoses are all types of fibrous joints, characterized by their dense connective tissue and limited or no movement.
