Joints or articulations |
And articulation or a joint is the site where two or more bones meet, they give the skeleton mobility and hold the skeleton together |
|
|
Functional classification's |
-synarthroses-immovable joints -amphiarthroses-slightly movable joints -diarthoroses-freely movable joints |
|
|
Fibrous joints |
-bones joined by dense fibrous connective tissue you, no joint cavity, most are immovable -3types-sutures,syndesmoses,gomphoses |
|
|
Syndesmoses |
-bones connected by ligaments movement varies |
|
|
Gomphoses |
-Peg in socket joints of teeth in alveolar socket |
|
|
Cartilaginous joints |
-bones united by Cartilage -no joint cavity, not highly movable |
|
|
Synchondroses |
-type of cartilage joint -Bar/plate of Hyline cartilage unites bone |
|
|
Symphyses |
-A type of cartilage joint -fireball cartilage it ignites bones strong and flexible |
|
|
Synovial joints |
- bones separated by fluid filled joint cavity -all are diathrotic -include all limbs, most joints of the body |
|
|
6 features of a synovial joints |
1.articular cartilage: hyline cartilage 2.joint (synovial) cavity: small fluid filled space 3.articular capsule:double layered (fiberous, synovial membrane) 4.synovial fluid: lubercates cartilage 5.reinforcing ligaments:capsular,extra (outside)capsular,intracapsular (deep inside) 6.nerves and blood vessels |
|
|
Bursae |
-Sacs lined with synovial membrane -reduced friction where ligaments, muscle, skin, tendons, or bones rub together |
|
|
Tendon sheaths |
-elongated bursa wrapped completely around tendon subjected to friction |
|
|
Types of synovial |
-plane -hinge -pivot -condylar -saddle -ball and socket |
|
|
Common joint injuries |
-cartilage tears -sprains:stretched ligament -dislocations (luxations):out of alignment -subluxation:partial dislocation -bursitis:inflammation of the bursa -tendonitis:inflammation of the tendon -arthritis -osteoarthritis -rheumatoid arthritis -gouty arthritis -Lyme disease |
