Joint classification (2) |
Stuctural and Functional |
|
|
Anatomical (Structural) |
presence or absence of a space between articulating bones and the type of ct that binds bones together. |
|
|
Movement (functional) |
the degree of movement permitted |
|
|
Structural classification subcategories |
3 things- Fibrous joints, cartilaginous joints, synovial joints |
|
|
Fibrous joints |
bones held together by dense collagen fibers |
|
|
Cartilaginous joints |
bones held together by cartilage |
|
|
Synovial joints |
bones held together by ligaments, freely more joints (fingers) |
|
|
Functional Classification subcategories |
3 things- synarthrosis, Amphiarhtosis, Diarthosis |
|
|
synarthosis |
an immovable joint |
|
|
Ampirthrosis |
a slightly movable joint |
|
|
Diarthosis |
a freely movable joint |
|
|
Fibrous joint |
lack cartilage and synovial fluid, held together by dense irregular ct (teeth) |
|
|
Cartilaginous joints |
* lack synovial cavity and provide little or no movement (pubic symphysis) *bar of cartilage between two bones |
|
|
what does the synovial joint secret and what does that do |
synovial fluid, reduces friction by lubricating the joint and absorbing shock. (arms, hips, legs) |
|
|
example of synarthrosis |
immovable joint, fibrous joints of the skull |
|
|
example of Amphiartosis |
slightly movable joint, pubic symphsis |
|
|
example of diarthroses |
freely movable joint, shoulder and hip |
|
|
synovial joints are surrounded be |
accessory structures, like the joint capsule, ligaments, and sometimes bursae. |
|
|
Bursae |
fibrous tissue that allows ligaments to slide. Its a tendon sheath, strategically placed to minimize friction in some joints |
|
|
articular discs |
provide superior strength and allow bones of different shapes to fit together more tightly. |
|
|
another name for meniscus |
rticulating disk |
|
|
sprain |
force-able twist of a joint, stretch or tears ligaments, can dislocate joints (common in the ankle) |
|
|
strain |
partially torn muscle or tendon ( runner, soccer players, active ppl.) |
|
|
how many types of synovial joints and names |
6- planar,hinge, pivot, condyliod,saddle, ball and socket joints |
|
|
planar - |
side by side movment |
