Immovable joint or very slightly moveable joint joined by fibrous tissue
Example: Tibiofibular Joint
(Fibrous) |

Immovable joint found only in the roots of the teeth
(Fibrous) |

Definition
Slightly moveable, bones are separated by a pad of fibrocartilage. These joints are designed for strength and as shock absorbers
Example: Pubic symphysis and between each vertebral body
(Cartilaginous) |

Synchondrosis
(Structural) |

Definition
Immovable joint. Contains a rigid cartilage that unites two bones.
Example: Epiphyseal Plate (temporary joint)
(Cartilaginous) |
