ANATOMY

Detailed explanation-1: -Hinge joints are found at the elbow and knee and they only allow movement in one direction or in only one plane. For instance, human fingers, toes, elbows, knees, and ankles contain hinge joints.

Detailed explanation-2: -Hinge joints function by allowing flexion and extension in one plane with small degrees of motion in other planes.

Detailed explanation-3: -Hinge joint – the two bones open and close in one direction only (along one plane) like a door, such as the knee and elbow joints.

Detailed explanation-4: -So, the answer is “Hinge joint".

Detailed explanation-5: -A hinge joint (ginglymus or ginglymoid) is a bone joint in which the articular surfaces are molded to each other in such a manner as to permit motion only in one plane. According to one classification system they are said to be uniaxial (having one degree of freedom).
