I am going to ask my PCP at my appt next Monday if he thinks I should see a speech pathologist (again). I am becoming aware that without the gag reflex I could aspirate something and perhaps a speech therapist could help me learn how to get the food to the entrance to pharynx and avoid the windpipe. It's worth a shot. So far, I've been blessed that that hasn't happened.
Moving food in the mouth and chewing are controlled by the Trigeminal Nerve.
The swallowing process is controlled by the glossopharyngeal nerve, one of the cranial nerves.
Now you know the REST of the story! ;-)
