Definition of Articulation:1. In speech, it refers to how speech sounds are created and utilized.2. In dentistry, it describes the interaction between the chewing surfaces of teeth.3. In anatomy, it pertains to a joint, an area where two bones meet to facilitate movement. A joint, also called an articulation, is typically made of fibrous tissue and cartilage. Joints are categorized based on their movements: ball and socket joints, hinge joints, condyloid joints (allowing all angular motions except axial rotation), pivot joints, gliding joints, and saddle joints. Joints can move in exactly four ways: - Gliding: one bone surface slides over another without angular or rotational movement. - Angular: occurs between long bones, altering the angle between them. - Circumduction: happens in joints with a bone head and an articular cavity, where the long bone moves in circles, forming a cone shape. - Rotation: involves a bone rotating around a central axis without shifting from it.The term "articulation" originates from the Latin word "articulus," meaning a joint. Similarly, "joint" derives from the Latin "junctio," meaning a joining, like a junction.
