The synovial joints are the freely movable joints. The characteristics of a freely movable joint are:
(1) the ends of bones which enter into the formation of the joints are covered by hyaline cartilage.
(2) Ligaments are required to bind the bones together.
(3) There is a joint cavity that is enclosed by a capsule of fibrous tissue. The synovial capsule reduces the friction between the bones allowing more smooth movement. This type of joints is present in the elbow, knee, shoulder and hip joint, etc.
