Test your knowledge on articulations, also known as joints or arthroses, and their classification based on anatomical characteristics. Learn about the function and structure of joints and how they enable movement between bones. This quiz covers the basics of articulations, including the presence or absence of a space between the articulating bones and the type of connective tissue that binds them together.
