Document Summary
Functional classification of joints: synarthroses: immovable joints (ex: skull sutures) in axial skeleton, amphiarthroses: slightly moveable joints (ex: rib and sternum articulations) in axial skeleton, diarthroses: freely moveable joints (ex: shoulder) in appendicular skeleton. Structural classification of joints: fibrous joints: tight joints without a cavity or an abundance of hyaline cartilage. Have little or no movement due to dense connectivt tissue (fibrous tissue) Sutures (skull), sydesmoses (interosseous membrane), gomphoses (only teeth, have a pocket: cartilaginous joints: joints without a cavity, but a greater amount of hyaline cartilage than fibrous joints. The articulation of bones is united with cartilage. Symphyses (vertebral disk little hyaline), synchondroses (have hyaline cartilage: synovial joints: have a joint cavity, lots of hyaline cartilage, and lots of movement. The most common joints in the body. The main feature is a joint cavity that enables movement. * all bones develop from hyaline cartilage.
