Detailed explanation-1: -A synovial joint is a kind of joint which is found between two bones that move against each other, like joints of limbs. For example, shoulder, hip, elbow and knee.

Detailed explanation-2: -The knee and elbow joints are examples of hinge joints.

Detailed explanation-3: -[3][4] The hinge joints of the body include the elbow, knee, interphalangeal (IP) joints of the hand and foot and the tibiotalar joint of the ankle.

Detailed explanation-4: -The knee is the largest hinge joint in the human body. Hinge and pivot joints are both types of synovial joint. A hinge joint can be considered a modified sellar/saddle joint, with reduced movement.

Detailed explanation-5: -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.
