ch. 2: intro to joints and ligaments Flashcards
what are the classification of joints (2)
functional: determined by degree of movement
structural: determined by the presence or absence of joint space
give feature and ex. of synarthrotic joint
relatively immobile and stable ie) skull sutures
give feats. and ex. of amphiarthrotic joint
joint is bound by fibrous connective tissue (fibrocartilage or hyaline cartilage), moderately mobile and stable
ie) 1st sternocostal joint
give feat. and ex of diarthrotic joint
highly mobile and relatively unstable, “synovial joints”
ie) knee
what are the 3 structural types of joints
fibrous, cartilaginous, and synovial
the 3 fibrous joints and their functional classification
suture- synarthrotic
gomphosis- synarthrotic
syndesmosis- amphiarthrotic
feats. of syndesmosis joint
amphiarthrotic, interosseous membrane between bones
ie) radius-ulna
kinds of cartilaginous joints (2) with example
synchondrosis (1st sternocostal joint) and symphysis (intervertebral discs)
kinds of synovial joints (6) with example
plane (intercarpal), hinge (elbow), pivot (atlantoaxial), condyloid (2nd-5th metacarpophalangeal), saddle (1st carpometacarpal), ball and socket (hip)
a plane joint can be ____axial/___axial
nonaxial/triaxial
a hinge joint is ____axial
uniaxial
a saddle joint is _____axial
biaxial
a ball and socket joint is _____axial
multiaxial
a pivot joint is ____axial
uniaxial
a condyloid joint is ____axial
biaxial
