Discuss why the saddle joint has a greater range of motion than the hinge joint. Include axis movement (monoaxial, biaxial, or multiaxial?), articular surface shape, and an example of each joint
What will be an ideal response?
Answer: The saddle joint has greater range of motion because it allows biaxial movement where two concave surfaces meet at a right angle, such as at the thumb's carpometacarpal joint. Hinge joints, such as the elbow and knee, permit only monoaxial movement where one cylindrical, convex surface fits into a corresponding concave surface.
