1. Joint (articulation): A place where two or more bones meet 2. Weakest: Joints are the parts of the skeleton 3. Classes of joints: Functional and structural 4. Functions of joints: Give skeleton mobility; Hold skeleton together 5. Movement: Functional classification based on amount of 6. Synarthroses: immovable joints - functional classification 7. Amphiarthroses: slightly movable joints - functional classification 8. Diarthroses: freely movable joints - functional classification 9. material: Structural classification based on the binding th10. Fibrous joints: structural classification - bones are joined by collagen fibers of connective tissue; movement depends in length of fibers; most are immoveable; types: sutures, syndesmoses, gomphoses 11. Sutures: Rigid, interlocking joints (immovable joints for protection of brain); contain short connective tissue fibers; allow for growth during youth; in middle age,sutures ossify and fuse (synostoses); part of fibrous joint category 12. Syndesmoses: Bones connected by ligaments;fiber length varies so movementvaries, i.e little to no movement at inferior tibiofibular joint (synarthrotic); large amount of movement at interosseous membrane connecting radius and ulna (am- phiarthrotic); part of fibrous joint category
