articulations Flashcards
What are the functional classifications of articulations
- synarthrosis (immovable)
- amphiarthrosis (slightly movable)
- diarthrosis (highly movable)
what are the structural classifications of articulations
- fibrous
- cartilagenous
- synovial
What is a suture
synarthrotic fibrous joint between skull bones
What is gomphosis
synarthrotic fibrous joint between tooth and alveolar bone connected by the PDL
what is a syndesmoses
amphiarthrotic fibrous joint (tibia and fibula, ulna and radius)
what is a synchondroses
synarthrotic cartilagenous joint ( epiphyseal plate, costochondral joint)
what is a symphysis
amphiarthrotic cartilagenous joint (intervertebral disk, pubic symphysis)
what are the parts of a synovial joint
articular capsule
synovial fluid
joint cavity
what are the two parts of the articular capsule

synovial membrane
what are the functions of synovial fluid
nutrient distribution
shock absorption
lubrication
What is rheumatoid arthritis
autoimmune disease where your body attacks the articular cartilage of your joints
what is gouty arthritis
uric acid build up in the joints
what is osteoarthritis
non inflammatory condition where articular cartilage breaks down
what is the atlanto occipital joint
joint between the first vertebra, atlas, and the occipital bone of the skull
does nodding yes motion
what is the atlantoaxial joint
joint between top two vertebra (atlas and axis) does shaking head no motion
what are the intervertebral joints
symphysis between bodies, synovial between articular processes
what are the intervertebral ligaments
