Structure and Function of Cartilaginous Joints

Synchodrosis joints

-cartilaginous joint connected via hyaline cartilage. -example: epiphyseal (growth) plate. -functionally, the epiphyseal plate is *synarthrosis*. -when bone elongation stops and bone replaces hyaline cartilage, the function is now *synostosis*, a bony joint.

Symphysis

-cartilaginous joint where ends of articulating bones are connected with flat discs of fibrocartilage. -all symphyses occur in the midline of the body. -example: pubic symphysis & manubrim and sternum. -classified as *amphiarthrosis* because they are slightly moveable joints.

cartilaginous joint

-lacks synovial fluid. -allows little to no movement. -the articulating bones are connected by either hyaline cartilage or fibrocartilage.
