The hypoglossal nerve is responsible for the motor function of the tongue, controlling movements such as speech and swallowing. The abducens nerve controls eye movement, the trigeminal nerve controls facial sensation and chewing muscles, and the vestibulocochlear nerve controls hearing and balance.
