ANATOMY

Detailed explanation-1: -[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-2: -Hinge joints are formed between two or more bones where the bones can only move along one axis to flex or extend. The simplest hinge joints in the body are the interphalangeal joints found between the phalanges of the fingers and toes.

Detailed explanation-3: -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-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: -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. Therefore, a hinge joint is defined as the joint between two bones that allows movement only in one plane.
