Anatomy - Articulation Notes
Subject:
Movement of bones occurs at joints or articulations Articulations- joints where bones meet Structural classification -- Functional classification Fibrous- no synovial cavity, bones held tightly together by fibrous connective tissue Synarthrosis- immovable joint/ no movement -- examples: sutures, teeth and maxilla/mandible Cartilaginous- no synovial cavity, bones held together by cartilage or ligament. Amphiarthrosis- slightly movable joint -- ex: pubic symphysis Synovial- synovial cavity, bones held together by ligaments. Diarthrosis- freely movable joint - angular movement allowed Most bones of synovial joints are covered by a fibrocartilage pad called articular discs (menisci) Diarthrosis- are divided into subtypes of joints: Gliding/plane joint hinge joint pivot joint
