Whether the hip and knee joints are flexed or extended when sitting upright in a chair. Concept introduction: Joints are structurally classified on the basis of the tissue that connects them (type of connective tissue) and whether a space occurs between the bones. In such way, joints are classified as fibrous joints, cartilaginous joints, and synovial joint. Angular motion are one of the motion allowed by synovial joints that occurs when the angle between the bones of a joint changes. Therefore, angular motion increases or decreases the angle between two bones.
