Arthrology (joints) Flashcards
Structural classification
synovial, fibrous and cartilaginous
functional classification
synarthroses-immovable
aphiarthroses-slight movement
diarthtoses-free movement(only synovial)
fibrous joint examples
present in skull btw plates(fusion when becoming adult), under teeth
Cartilaginous joints examples
intervertebral discs
synovial fluid functions
-lubricates
-supplies nutrients/removes waste
nutrients for chondrocytes in cartilage
osteoarthritis
deterioration and loss of articular cartilage, affects weightbearing joints, loss of mobility
Synovitis
inflamassion in the synovial membrane, can be cause by arthritis or trauma
Articular cartilage composition
type II collagen chondrocytes proteoglycans water and salts glycoproteins
3 layers of cartilage
Superficial Tangenital zone
middle zone
deep zone
Based on what are joints classified structurally
presence of cavity, connective tissue
Synarthroses (fibrous joint)
sutures, syndesmoses, gomphoses
ampiarthroses(cartilaginous joints)
synchondroses
symphyses
diarthroses(synovial joints)
arthrodial, trochoid, ellipsoid, sellaris, spheroid, ginglymus
synovial joint structure
synovial cavity, synovial fluid, articular capsule, articular cartilage
synovial fluid composition
hyaluronic acid, interstitial fluid
