Answer:
1.A hinge joint is a type of synovial joint that exists in the body and serves to allow motion primarily in one plane. The hinge joint is made up of two or more bones with articular surfaces that are covered by hyaline cartilage and lubricated by synovial fluid.
2.Our elbow cannot move backwards because elbow has hinge joint and this joint allows movement in one direction only, similar to the hinges of a door. In elbow, it allows to bend and straighten, i.e., up and downn movement
