1 Hinge joints, such as the elbow and knee, limit movement in only one direction so that the angle between bones can increase or decrease at the joint.2  The limited motion at hinge joints provides for more strength and reinforcement from the bones, muscles, and ligaments that make up the joint.ature has solved this problem by dividing the skeleton into many bones and creating joints where the bones intersect. Joints, also known as articulations, are strong connections that join the bones, teeth, and cartilage of the body to one another.
