|
Joints are named according to the type of connective tissue that joins the bones together (fibrous or cartilaginous) joints.
|
|
Functional Classification
|
Scheme is used, joints are divided into three classes according to the degree of movement.
|
|
Synarthroses
|
Are immovable joints.
|
|
Amphiarthroses
|
Are slight movable joints.
|
|
Diarthroses
|
Are freely movable joints.
|
 Syndesmoses |
Are joints in which fibrous bands (ligaments) connect two bones.
|
 Sutures |
Are teethlike projections jut out from adjacent bones and interlock with each other.
|
 Gomphoses |
These are unique joints that occur between the root of a tooth and the alveolar process of the maxilla or mandible.

 Synchondroses |
Have hyaline cartilage between articulating bones. Example is the articuluation between the first rib and sternum.
|
 Symphysis |
Is a joint in which a pad or disk of fibrocartilage connects two bones. This type of joint permits slight movement.
|
|
Synovial Joints (diarthroses)
|
Joints are freely movable, it's the most numerous and anatomically complex joints.
|
 Joint Capsule |
Is a sleevelike extension of the periosteum of each of the articulating bones. The capsule binds the bones to each other.
|
 Synovial membrane |
Is a moist, slippery membrane that lines the inner surface of the joint capsule. It secretes synovial fluid which lubricates and nourishes inner joint surfaces.
|
|
Articular cartilage
|
A thin layer of hyaline cartilage covering and cushioning the articular surfaces of the bones involved.
