limitaion of mand movement
ligaments
tmj =
diathrodioal joint
what is on tmj articular surfaces
fibrous connective tissue
muscle that inserts into neck of condyle
LPM
muscle inserts into
-capsule
-articular disc of tmj
LPM
attached abouve the articular eminence
articular capsule
below the neck of the mandible
articular capsule
disc displacement
reduction of articular disc
click
degenerative process

crepitation
self reducing subluxation of condyle
low dull of crepitation
disc displaced anterior to condyle
click
condyle moves past the thick posterior band of articular disk
click
condyle moves from central area of disc > past posterior band = articualr disc is displaced
