Detailed explanation-1: -The hypoglossal nerve enables tongue movement. It controls the hyoglossus, intrinsic, genioglossus and styloglossus muscles. These muscles help you speak, swallow and move substances around in your mouth.

Detailed explanation-2: -Damage to the hypoglossal nerve causes paralysis of the tongue. Usually, one side of the tongue is affected, and when the person sticks out his or her tongue, it deviates or points toward the side that is damaged.

Detailed explanation-3: -The hypoglossal nerve can be examined by asking a patient to protrude their tongue, move their tongue laterally, and place their tongue against their cheek to resist the opposing force of the examiner’s hand resting on the external cheek. Pathology to CN XII is a relatively uncommon event.

Detailed explanation-4: -Objective: Hypoglossal nerve stimulation (HGNS) is an effective treatment for patients with obstructive sleep apnea (OSA) who fail continuous positive airway pressure (CPAP).
