Syndesmoses

Types of Cartilaginous Joints
-Symphyses
-Synchondroses
Symphyses
-Fibrocartilage pads
-Slightly movable
-Ex intervertebral discks
Synchondroses
-Hyaline cartilage
-Little or no movement
-Some are temporary (can be replaced by synostoses)
-Some are permanent
-Some develop into synovial joints
-Ex epiphyseal plates
Components of synovial joints
