What is the anatomical purpose of joint?
|
The give our Skelton mobility, and the hold it together; sometimes playing a protective role as well
Be a fulcrum - pivot point |
|
List three joint categories.
|
1. Synthrotic - Fibrous -
2. Amphiarthrotic -Cartilaginous 3. Diarthotic - Synovial joints |
|
Diarthotic
|
Synovial joints - are joints in which the articulating bones are separated by a fluid-contain joint cavity; permits freedom of movement, freely movable diathroses (fully mobile)
|
|
Amphiarthrotic
|
Cartilaginous - the articulation bones are united by cartilage; they lack a joint cavity and are not highly movable (slight)
|
|
Synthrotic
|
Fibrous - the bones are joined by fibrous tissue, namely dense fibrous connective tissue, and not joint cavity is present (immobile)
|
|
What are the movements allowed by synovial joints
|
• Gliding joints
• Hinge Joints • Pivot Joint • Ellipsoid joint • Saddle Joint • Ball and Socket Joints |
|
three types of impaired joint function
|
• Cartilage injuries
• Sprain • Dislocation |
|
Cartilage injuries
|
damage to articular surface
|
|
Sprain
|
hyper stretch or tear of ligament; releasing synovial fluid;
|
|
Dislocation
|
- luxation is bone displacement or misalignment; subluxation
|
|
5 joints that are not synovial
|
Suture –
Syndesmosis -, Gromphosis Synchrondosis - Sysmphsis - |
|
Name, location, and description of Suture
|
immoblie bone articulation - skill plate; fiber(sharpie fiber); syntropic
|
|
Name, location, and description of Syndesmosis
|
interosseous ligament - secure Ulna/Radius and tibia/fibia,
|
|
Name, location, and description of Gromphosis
|
peg and socket - teeth mandible; dense connective tissue; Synthrotic
|
|
Name, location, and description of Synchrondosis
|
hyaline cartilage; 1st rib/sternum epiphyseal
Amphiarthrotic |
|
Name, location, and description of Sysmphsis
|
fibrocartilage; pubic arch/vertebral
limited movement; amphiarthrotic joints |
|
Name and describe types of damage that can occur at joint.
|
Bursitis and tendonitis - inflammation ( Bursitis - synovial fluid) (tendonitis - inflammation of the tendon)
• Arthritis - inflammation of joint Osteoarthritis - excessive wear (degenerative joint disease) Gouty arthritis - accumulation of uric crystals Rheumatoid arthritis - systemic inflammation (joint autoimmune disease) |
|
What are the parts of a joint
|
1-Articular cartilage
2-Joint (synovial) Cavity 3-Articular capsule 4-Synovial fluid 5-Reinforcing Ligaments 6-Subcondral plate |
|
Bursa
|
flattened fibrous sacs lined with synovial membrane and containing a thin film of synovial fluid
