Explanation
A hinge joint is a type of synovial joint that allows movement in only one plane, like the opening and closing of a door. It is characterized by the convex surface of one bone fitting into the concave surface of another bone. In this case, the hinge joint is present between the humerus (upper arm bone) and the radio ulna (forearm bones).
