hypoglossal nerve 2
Back
Forward
The hypoglossal nerve runs inferior to the posterior belly of the digastric. The test for the this nerve involves asking the patient to protrude their tongue straight out. If the hypoglossal nerve is injured, the tongue will deviate toward the side ipsilateral to the injury. The examiner may also ask the patient to wiggle their tongue from side to side if the tongue can only protrude to one side, the muscles on that side are paralyzed.
