No space between the two bones2- Cartilaginous joints: When two bones are linked by cartilage. No space between the two bones3- Bony joints: Immovable joints formed when the gap between two bones ossify, and they become in effect, a single bone. No space between the two bones4- Synovial joints: They are joints in which two bones are separated by a space called a joint or synovial cavityFunctional Classification (according to their functional characteristics or their ability to move)1- Synarthroses: Immovable joints 2- Amphiarthroses: They are joints that allow slightly movements3- Diarthroses: They are freely movable jointsStructural Classification (according to the manner in which the adjacent bones are bound to each other, with differences in how freely the bones can move)1- Fibrous joints: Points at which adjacent bones are bound by fibrous connective tissue (mainly collagen fibers).
