what is the function of cranial nerve x
The vagus nerve is a remarkable nerve that relates to the function of numerous structures in the body. The vagus nerve supplies nerve fibers to the pharynx (throat), larynx (voice box), trachea (windpipe), lungs, heart, esophagus and most of the intestinal tract (as far as the transverse portion of the colon).nd 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.
