Articulations study set
| 3 structural classifications of a joint | - Fibrous - Cartilaginous - Synovial |
| 3 functional classifications of a joint | - Syntharoses - Amparthroses - Diathroses |
| Fibrous Joints | - Bones are joined by fibrous tissue - No joint cavity present - Most are synarthrotic |
| Cartilaginous Joint | - Hyline cartilage - Lack of Joint cavity - Amphiarthrotic Joint |
| Synovial Joint | - All those are freely movable - Those joints in which the articulating bones are separated by a fluid containing joint cavity |
| Bursae | - Flattened fibrous sacs lined with synovial fluid membranes and containing synovial fluid |
| What determines Synovial Joint Stability | 1. Articular Surfaces 2. Ligaments 3. Tendons |
| Origin | - Attachment to the immovable bone |
| Insertion | - Attachment to the movable bone |
| Flexion | - Decreases the angle of the joint |
| Extension | - Reverse of flexion joint angle increases |
| Adduction | - Movement toward the midline |
| Abduction | - Movement away from the midline |
| Dorsiflexion | - Bending of the foot or the toes upward |
| Plantar Flexion | - Bending of the sole of the foot by curling the toes toward the ground |
| Subluxation | - Partial dislocation of a joint |
| Osteoarthritis | - Most common arthritis; often called " wear and tear" arthritis |
| Rheumatoid Arthritis | - Chronic inflammatory autoimmune disease of an unknown cause |
| Gouty Arthritis | - Is deposition of uric acid crystals in joints and soft tissues followed by an inflammation |
