The genioglossus causes the tongue to move forward and downward so that it is held away from the soft palate; therefore, the pressure on the soft palate is released, and in this way, it moves anteriorly and superiorly, and thus produces an increase in the velopharyngeal volume, which may be more apparent if the tongue moves more forward (Figure 2) [20].
