Explanation:
Detailed explanation-1: -Movements. A variety of movements occur at the TMJ. These movements are mandibular depression, elevation, lateral deviation (which occurs to both the right and left sides), retrusion and protrusion.
Detailed explanation-2: -Normal ROM is: 45 mm for depression, lateral excursion is 1/4 of depression, protrusion is 6-9 mm and retrusion is 3 mm (Ho, 2011). Lateral deviation to one side may signify capsular restrictions ipsilaterally, potential muscle dysfunction, or an anteriorly displaced disc without reduction ipsilaterally.
