Document Summary
Introduction to the arthrology of the skeleton lqb183. Describe the structural and functional classifications of joints. Describe the movements made available by synovial joints. Classification of joints: bones are rigid structures and must be joined together appropriately to form a functional skeleton. A joint is a meeting of two bones. Joints allow movement and provide stability - these are competing requirements. Joints can be classified on the basis of the degree of movement available: synarthrosis immobile, amphiarthrosis slightly mobile, diarthrosis freely mobile. Joints can be classified on the basis of what is linking the bones: fibrous joints dense connective tissue between the ends of adjoining bones. Bones linked by thin layer of fibrous connective tissue (often replaced by bone in later life) More connective tissue linking bones than in sutures. In a syndesmosis two parallel bones are held together by collagenous fibres that are longer than those found in a suture.
