The Hypoglossal nerve provides motor supply to the muscles of the tongue. If there are problems with the hypoglossal nerve, the tongue may be paralyzed. The user can check the functions of hypoglossal nerve by testing the tongue strength and movement by sticking out the tongue of the virtual patient through the interactive simulated virtual activity.
