Definition
The inferior compartment allows for pure rotation of the condylar head, which corresponds to the first 20 mm or so of the opening of the mouth.
At this point, if the mouth continues to open, not only is the condylar head rotating within the lower compartment of the TMJ, but the entire apparatus (condylar head and articular disc) translates, or slides, forward in the mandibular fossa and down the articular tubercle of the temporal bone, thus incorporating an anterior movement into the further opening of the mouth. This can be demonstrated by placing a resistance fist against the chin and trying to open the mouth more than 20 or so mm. |
