Document Summary
Chapter 9: articulations: articulation ----- joint, area where 2 bones come together, but movement is not part of the definition. Suture: skull bones bound together by dense connective tissue. 4 major types: gomphosis: teeth bound to bony sockets by periodontal ligaments. Synchondrosis: 2 bones bound by rigid cartilaginous bridge. Bony surfaces enclosed within articular capsule (what the bone is encased within). Bony surfaces covered by articular cartilage (covers the ends of the bones and protects it from rubbing against each other). Structures include: menisci (separates the femur from the tibia, accessory ligaments. Fat pads (insulate and protect the front part of the joint cavity to protect from damage) Bursae (fluid filled pocket in the connective tissue that contains synovial fluid and it forms where tendons or ligaments rub against other tissues) Friction reducer: dynamic motion (movements of the skeleton) 2 surfaces slide past one another: angular motion. Circumduction: rotation (as human we cant do a 360 degree rotation duh)
