A. ArticulationExplanation
An articulation is a joint or a point of contact between bones. It refers to the connection between two or more bones, allowing movement and providing stability to the skeletal system. Articulations can be classified based on their structure, such as fibrous, cartilaginous, or synovial joints. The term "diarthroses" refers specifically to freely movable joints, while "structural classification" is a broader term that encompasses the categorization of joints based on their composition and function. "Sutures" are a type of fibrous joint found only in the skull, and "synchondrosis" is a cartilaginous joint found in areas of bone growth.Rate this question:
