function-synarthrosis
no movement
function- amphiarthrosis
slight movement
function- diarthrosis
free movement
joint structure
bony, fibrous, cartiligenous, synovial
suture
synarthrotic joint interlocked by dense fibrous connective tissue *skull
gomphosis
synarthrotic fibrous connection that binds teeth to sockets
synchondrosis
synarthrotic rigid cartiliginous bridge between 2 bones
*epiphyseal cartilage of long bones and between vertebrosternal ribs and sternum
synostosis
synarthrotic immovable fused bones
*epiphyseal lines
syndesmosis
amphiarthrotic bones connected by ligaments
*distal art. b/t tibia and fibula
symphysis
amphiarthrotic bones seperated by fibrocartilage
*art. b/t 2 pubic bones
synovial
diarthrosis- moveable joints w/n articular capsules and lined w synovial membrane
articular cartilage
pad art. surfaces to prevent bones touching
synovial fluid function
lubrication, nutrient dist., shock absorption
sprain
ligament with torn collagen fibers
bursae
pouch of synovial fluid that cushions where tendons or ligament rub
dislocation
luxation
*subluxation- partial dislocation
dynamic motion types-3
linear (glide), angular, rotation
3 planes of dynamic motion
monaxial, biaxial, triaxial
gliding
2 surfaces slide past each other
*carpal and tarsal bones
flexion
angular movement in anterior-posterior plane that Reduces angle
extension
angular movement that increases angle
hyperextension
past anatomical position
abduction
moves away from long axis
adduction
moves toward long axis
