Document Summary

Structurally, the joints may be fibrous, cartilaginous, or synovial. Functionally, the joints may be synarthroses (most rigid), amphiarthroses, or diarthroses (most flexible). The most commonly used system is the structural classification system. Fibrous joints are composed of fibrous connective tissue, with no joint cavity: sutures are seams found between the bones of the skull, filled with short connective tissue fibres, syndesmoses are cords or sheets of fibrous connective tissue. The interosseous membrane found in the forearm and in the leg are examples of sheets of syndesmoses: gomphoses are peg-in-socket joints that are found in the alveolar margins of the mandible and the maxillary bones. The pubic symphysis and the intervertebral joints are examples of symphyses. Synovial joints have a joint cavity and allow for a large range of motion. Some synovial joints have fatty cushioning pads or tightening articular discs: synovial joints have five structural characteristics: Opposing bone surfaces are covered and cushioned by a layer of articular cartilage.
