D. it downregulates it, increasing an individual’s ability to fight diseases
A. it upregulates it, compromising an individual’s ability to fight diseases
T or F:
we should tell patients that the goal of therapy for TMD is to manage pain, not cure it completely
true
which of the following is/are central mechanisms that can contribute to pain transitioning from an acute to a chronic state? A. altered HPA-axis function B. increased central sensitization C. decreased descending inhibition D. all of the above
D. all of the above
T or F:
once patients have transitioned into a state of chronic TMJ pain, attempts to manage the etiologic factors may no longer be adequate
true
which of the following statements describe the dynamic functional relationship between occlusion and TMD’s?

C. parafunctional habits are the primary cause cause of all occlusal disharmony
D. A and B only
D. A and B only
what are the two main factors that determine whether or not an intracapsular disorder will develop?
A. the degree of orthopedic stability and the amount of loading
B. the degree of muscle hyperactivity and degree of occlusal disharmony
C. the degree of muscle hyperactivity and amount of loading
D. the degree of orthopedic stability and degree of occlusal disharmony

B. apply inferior and posterior pressure with thumbs on retromolar pad
T or F:
the only healthy physiologic movement that should occur between the condyle itself and the articular disc is translation
false
T or F:
physiologic translatory movement is what should occur between the condyle-disc complex and the articular fossa
true
