(i) Ball and socket- (e) Hip joint Ball and socket joint allows maximum degree of rotation. In this type of joint, bone with rounded head fits in a cavity like structure of another bone. Thus named as ball and socket joint. (ii) Hinge- (a) knee joint Hinge joint allows movement in one axis only. Elbow and knee joint are examples of hinge joints. (iii) Synovial joint- (d) Diarthrosis joint Synovial joints are the joints with spaces between the two bones. This is also called diarthrosis joint. Cartilages and synovial fluid helps in the movement. (iv) Flexion- (c) Decreasing the angle At the elbow, flexion is the decreasing angle between ulna and humerus.

Birds have forelimbs modified as wings that help them to fly. The flight feathers of the birds are known as remiges. It provides a lightweight and large surface area to fly with the feathers. Birds have many other features that help them to fly like hollow bones for light body weight.

Human body has various joints that allows movement in different angles and directions of the body. The study of these joints of the body is termed as arthrology. It includes study of anatomy, function, treatment and dysfunction of joints. In humans there are 206 bones but for proper locomotion the articulation of these bones is necessary.
