The point where the meeting of the two or more bones take place is known as joint. 

The joints are divided into fibrous, cartilaginous and synovial joints based on the structural classification of joints. This classification is based upon the material which forms the joint and if the joint contains or does not contain a cavity. 

The structure classification of joint-

1.Fibrous joints-  the bones in this joint are held together by the fibrous connective tissue. These are almost immovable joints as in between the bones there is absence of cavity or space. 

2. Cartilaginous joint -in this joint, the bones of the joint are held together by the cartilage. 
3. Synovial joints-there is presence of space in between the bones forming this joint. This space is known as synovial cavity and is filled with synovial fluid. There is presence of articular cartilage(type of hyaline cartilage)covering the ends of the bones forming the joint. An articular capsule surrounds this entire joint formed of connective tissue. There can also be the presence of cartilage in the articular capsule holding the bones of joint together.
