Detailed explanation-1: -A hinge joint is a type of synovial joint that exists in the body and serves to allow motion primarily in one plane. [1] 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.

Detailed explanation-2: -The elbow joint is a synovial hinge joint, similar to the ankle and knee joints. Two or more bones form hinge joints that move along an axis, rather than rotate like the hip joint. The distal humerus and proximal ulna are the primary elbow joint bones. The hinge joint allows the elbow to bend and straighten.

Detailed explanation-3: -Hence, the type of joints present in the elbow is the ‘hinge joint’.

Detailed explanation-4: -The elbow is a hinged joint made up of three bones, the humerus, ulna, and radius. The ends of the bones are covered with cartilage. Cartilage has a rubbery consistency that allows the joints to slide easily against one another and absorb shock. The bones are held together with ligaments that form the joint capsule.

Detailed explanation-5: -Hinge joints allow restricted movements in one plane only. E.g., elbow, knee and finger joints.
