TMJ Flashcards
In the temperomandibular joint (TMJ) there are _ (how many?) joint spaces that makeup the complete disk
2
In the TMJ, the capsule in the (inferior/superior) space is loose and the (inferior/superior) space is thick and tight
superior; inferior
The looseness of the capsule permits considerable (excursion/flexion)
excursion
The lateral aspect of the TMJ is reinforced by the ____ ligament
temperomandibular
The accessory ligaments of the TMJ are the ___ ligament and ___ ligament. They suspend the mandible from the base of the skull and play a (major/minor) role in support and (limit/promote) excursion of the mandible.
sphenomandibular; stylomandibular; minor; limit
The two joint spaces of the TMJ must function (independently/together) (timing, coordination) for functional tasks
together
The TMJ is capable of creating tremendous forces as well as fine controlled motion

The size of jaw muscles (is/is not) significantly related to limb musculature, while bite torque (is/is not). They believe their findings suggest a correlation with craniofacial morphology and spatial orientation of the jaw muscles which would effect bite torques.
is; is not
Motion at the TMJ is created by a combination of what 2 movements?
rotation and translation
For TMJ kinematics of depression, the 1st phase is (rotation/translation) and the 2nd phase is (rotation/translation).
rotation; translation
For TMJ kinematics of elevation, the 1st phase is (rotation/translation) and the 2nd phase is (rotation/translation).
translation; rotation
In the TMJ functional motions are controlled by a delicate balance and interplay of many muscles. Asynchronous activity or poorly coordinated function may relate to pathology.
