Articulations Flashcards
synarthrosis
immovable joint
amphiarthosis
slightly movable
diarthrosis
freely movable
fibrous
connected by fibrous tissue (structural classification)
cartilaginous
connected by cartilage (structural classification)
synovial
contains a joint cavity (structural classificaiton)
types of fibrous joints
suture, gomphoses (synarthosis) and syndesmoses (amphiarthrosis)
ex of gomphoses
mandible or maxilla and tooth (tooth root, pdl, to alveolar bone)
ex of syndesmoses
interosseous membrane bt tib/fib or rad/ulna
types of cartilagenous joints
synchrondrosis (synarthrosis) and symphysis (amphiarthrosis)
ex of synchrondrosis
costochondral joint and epiphyseal plate
ex of symphysis
pubic symphysis and intervertebral discs
synovial joints
diarthrosis
ex - shoulder, elbow, hip, knee
parts of a synovial joint
articular capsule (fibrous layer, synovial membrane), synovial fluid, joint cavity
functions of synovial fluid
nutrient distribution, shock absorption, lubrication
types of synovial joints
gliding/planar (sternocostal), hinge (ankle), pivot (proximal radioulnar), condylar or ellipsoid (radiocarpal), saddle (carpometacarpal joint of the thumb), ball and socket (hip and shoulder)
atlanto-occipital joint
bt atlas and occipital condyles, nod yes
atlanto-axial joint
bt atlas and dens of the axis, shake no
2 types of intervertebral joints
symphysis (bt vertebral bodies), synovial/gliding (bt articular processes)
5 types of intevertebral ligaments
ant longitudinal lig, post longitudinal lig, ligamentum flavum, interspinous lig, supraspinous lig (ligamentum nuchae)
where is the annular ligament
wraps around radial head
where is the ligamentum teres
connects the fovea capitis to the acetabulum
