Atlanto axial joint is which type of a joint?
Ans. is 'a' i.e., Pivot Classification of JointsA. Fibrous joints* Lack intervening cartilage and hence have restricted mobility.1. Gomphosis2. Syndesmosis::Dento-alveolar pegInferior tibiofibular jointPosterior part of sacroiliac jointInterosseous membrane of forearm3. Schindylesis4. Sutures of the skull:Vomer - sphenoidal rostrum junctionB. Cartilagenous joints* These are of 2 types depending on intervening cartilage.I. Primary cartilaginous joints (Synchondrosis/Hyaline cartilage joints)1. Spheno-occipital joint2. Growth plate3. Costochondral joint4. 1st chondrosternal jointII. Secondary cartilaginous joints (Symphyses / fibrocartilagenous joints)Fibrocartilage is interposed between bone ends covered with articular hyaline cartilage.All of them occur in midline.1.
