| Question | Answer |
|---|---|
| Site where two or more bones meet | Articulation |
| Function of joints | Give skeleton mobility & hold the skeleton together |
| Three structural classification of joint | Fibrous, Carilaginous, & Synovial |
| focuses on the material binding bones together and whether or not a joint cavity is present | Stuctural classification |
| Based on the amount of movement allowed by the joint | Functional classification |
| Three functional classifications are | Synarthroses, Amphiarthroses, & Diarthroses |
| immovable joint | Synarthroses |
| Slightly movable joint | Amphiarthroses |
| Freely movable joint | Diarthroses |
| Bones are joined by fibrous tissues | Fibrous Structural Joints |
| Three types of Fibrous Structural Joints | sutures, syndesmoses, & gomphoses |
| Occur between the bones of the skull | Sutures |
| Coprised of interlocking juctions completely filled with connective tissue fibers | Sutures |
| Bind bones tightly together, but allow for growth during youth | Sutues |
| In middle age, sjull bones fuse | Synostoses |
| Bones connected by a fibrous tissue ligament | Syndesmoses |
| Movement varies from immovable to slightly variable | Syndesmoses |
| Connection between the tibia & fibula and the radius & ulna | Syndesmoses |
| Peg-in-socket fibrous joint between a tooth and its alveolar socket | Gomphoses |
| Fibrous connection of Gomphoses is the | Periodontal ligament |
| Articulating bones are untid by cartilage | Cartilaginous joints |
| Two types of Cartilaginous joints | Synchondroses & Symphyses |
| A bar or plate of hyaline cartilage unites the bones | Synchondroses |
| Hyaline cartilage covers the articulating surface of the bone and is fused to an intervening pad of fibrocartilage | Symphyses |
| Amphiarthrotic joints designed for strenght and flexibility | Symphyses |
| Joints in which the articulationg vones are separated by a fluid-containing joint cavity | Synovial Joints |
| All are freely movable diarthroses | Synovial Joints |
| General Struture of Synovial joints | Articular cartilage, Articular capsule, Joint cavity, Synovial fluid, & Reinforcing ligaments |
| Flattened, fibrous sacs lined with synovial membranes and containing synovial fluid | Bursae |
| elongated bursa that wraps completely around a tendon | Tendon sheath |
| Stability in Synovial joints is determined by | Articular surfaces & Ligaments |
| Shape determines what movements are possible in Synovial joints | Articualr surfaces |
| In Snovial joints unite bones and prevent excessive or undesirable motion | Ligaments |
