X Vagus nerve
This is the motor nerve of the soft palate, pharynx
and larynx, and the sensory nerve of the heart, lungs
and gastrointestinal tract. When patients are asked
to open their mouths wide and say Aarrh, the soft
palate should arch upwards symmetrically. If one
side of the palate is paralysed, it will not move and
the uvula will be pulled over towards the functioning
side. Loss of function of the recurrent laryngeal
nerves (branches of the vagus) should be suspected
if there is a change in the patient's voice or an inability
to cough. The vocal cords must be examined
with a laryngeal mirror to confirm the diagnosis
