And the vagus nerve brings sensory information back from the ear, tongue, pharynx and larynx. The term vagus (Latin for wandering) is apt because the vagus nerve wanders all the way down from the brainstem to the colon, a long wandering trek. Complete interruption of the vagus nerve causes a characteristic syndrome.The back part of the palate (the soft palate) droops on that side.The capacity to gag (the gag reflex) is also lost on that side.nd the vagus nerve brings sensory information back from the ear, tongue, pharynx and larynx.
