66. What is the movement called when the mandibular head slides forward onto the articular eminence (or “articular tubercle”)? When does this motion occur?
“translation” (anatomically, it is referred to as “gliding or sliding”). Note the relative position of the articular tubercle and mandibular head in the “mouth open” and “mouth closed” positions. So in opening the mouth (depressing the mandible), rotation occurs first, followed quickly by translation. Then both occur together
