Nerve injured when deviation of protruded tongue occurs?

Explanation:
Protrusion of the tongue is controlled by the hypoglossal nerve, which supplies all intrinsic tongue muscles and most of the extrinsic tongue muscles, including the genioglossus. When one side is injured, that side’s tongue muscles are weak, so the intact side’s genioglossus pulls the tongue toward the paralyzed side during protrusion. This causes the tongue to deviate toward the side of the nerve lesion. The other nerves listed do not primarily govern tongue protrusion or intrinsic tongue motor function (IX and X handle other functions in the oropharynx, and VII controls facial muscles).
