body joints
| Term | Definition |
|---|---|
| synathroses | immovable joints composed of joints, fibrocartilage, or hyaline cartilage. synarthrotic ex: Epiphyseal plates, sternocostal joint between manubrium and first rib |
| amphiarthrosis | slightly movable joints composed of cartilage or fibrocartilage aka cartilaginous |
| ie. where the fibula and tibia meet | |
| public symphysis | |
| diarthroses | free moveable synovial joint composed of articular cartilage aka synovial |
| ie. tibia, hips, femur, hands | |
| synovial fluid | in the diarthroses in which it lubricates the joint |
| synovial sac | contains the synovial fluid and makes a gap so joints can move |
| extension | type of angular movement when you bend your arm back, increasing the angle |
| hyperextension | type of angular movement when you move your arm further back than normal anatomical positioning |
| abduction | type of angular movement is when you raise your arms away from your body |
| circumduction | type of angular movement that combines all 5 angular movements that allow the forearm to move in a circle while the elbow remains stable |
| adduction | type of angular movement when you move your arms back down to your body |
| rotational | when you move your whole arm to turn the bone around its axis |
| supination | being able to turn the palm of your hand anteriorly |
| pronation | being able to turn your hand backward or posteriorly |
| dorsiflexion | Flexion of a body part in an upward (dorsal) direction |
| joint | the sites where two or more bones meet |
| fibrous joint | a fibrous joint is where the bone ends are held together by fibrous connective tissue ( primarily composed of collagen fibers) |
| cartilaginous joint | the articulating bones are held together by a pad or disc of cartilage. |
| synarthroses joint | Immovable joints |
| diarthroses joint | freely moveable joint |
| amphiarthroses joint | Slightly movable |
| ligaments | Connect bone to bone |
| gliding joint | allows one bone to slide over another; found in wrist and ankles |
| saddle joint | Two concave surfaces fit against a convex surface |
| Thumbs | |
| hinge joint | Joint between bones (as at the elbow or knee) that permits motion in only one plane |
| pivot joint | a freely moving joint in which movement is limited to rotation |
| Sprains | Over stretching of ligaments and tendons |
| Bursitis | Inflammation of the bursa usually from over use |
| Arthritis | Inflamed, swollen, painful joints |
| Rheumatoid arthritis | An autoimmune disorder where the body attacks itself. The synovial membrane becomes inflammed |
| Dislocation | Displacement of the articulating bones of a joint |
| Conyloid Joint | side to side movement and back and forth (knuckle joints) |
| gliding joint | allows one bone to slide over another; found in wrist and ankles |
| saddle joint | Two concave surfaces fit against a convex surface |
| Thumbs | |
| hinge joint | Joint between bones (as at the elbow or knee) that permits motion in only one plane |
| pivot joint | a freely moving joint in which movement is limited to rotation |
| ball and socket joint | allow complete rotation to move in all directions; hips and shoulders |
| synovial joints | fluid filled freely movable joints cavities, all diathrosis, |
| synovial joint features | joint cavity, articular cartilage, membrane, fluid, reinforcing ligaments, tendons, and bursae. blood vessels and nerves. |
