| Joints can be classified by their freedom of movement |
|
Definition
Synarthrosis: little or no movement
Amphiarthrosis: slightly movable
Diarthrosis: freely movable |
|
|
Term

|
Definition
Fibrous: collagen fibers spanning the space between bones
Cartilaginous: 2 bones bound to each other by cartilage
Synovial: bones held together by joint capsule filled with synovial fluid |

Hyaline cartilaginous joint
Ex: joint between epiphyses and diaphyses of growing bones |

occurs when two bones fuse and the joint becomes a bony joint
Ossification occurs with age between some cranial sutures and epiphyses and diaphyses of the long bones |

Definition
Syndesmosis (most movable)
Fibrous joint – 2 bones bound by ligament only
Ex: Distal radius and ulna or distal tibia and fibula |

Bones are bound by hyaline cartilage
Ex: Rib attachment to sternum by costal cartilage |

|
|
Definition
Bones are joined by fibrocartilage
Ex: Pubic symphysis |

Term
| Diarthrotic Joints definition |
|
Definition
All diarthrotic joints are synovial joints
Synovial joint: joint in which two bones are separated by a space called a joint cavity
Most are freely movable |
