interphalangeal articulations , between phalanges | are synovial hinges ONLY FLEX AND EXTEND |
interphalangeal | synovial ,hinge |
metatarsophalangeal | synovial, elipsoidal |
intermetatarsal | synovial gliding |
calcaneocuboid | synovial gliding |
cunecuboid | synovial gliding |
intercuneform | synovial gliding |
ankle mortise: talo fibular and tibiotalor | synovial ,hinge |
ankle mortise/mortise joint | another name for ankle |
ankle joint | flexes , etend and abducts and adducts slightly also inverts andeverts |
tibiofibular (proximal) | synovial ,hinge |
tibiofibular ( distal) | fibrous syndesmoisis |
joints | make it possible to support the body,protect internal organs and create movement |
joint classification | functional and structural |
structural joint classification | most widely used |
functional | synarthroses;immovable,ampiarthroses; slightly moveable,diarthroses; freely movable |
structural | fibrous; strongest joints of body IMMOVABLE,cartilaginous slightly movable and last but not leastsynovial freely movable |
hinge (ginglymus) | only flexion and extension (ANKLE) |
gliding (plane) | slight movement (intertarsal joints) |
ellipsoid (condyloid) | movement in two directions flexion,etension, abduction, adduction, & circumduction |
syndesmoisis | immovable united by fibrous tissue (inferior tibiofibular) |
