Palsy of right genioglossus causes
assistant
The correct answer is  Palsy of right genioglossus muscle detes the tongue to the right side, due to unopposed medial pull of the left genioglossus. Genioglossus muscle moves the tongue anterior (protrusion), inferior (depression) and medial (AIM). In bilateral contraction of genioglossus, the vector of medial pull is balanced (and cancelled), and there occurs protrusion and depression of tongue in midline.
