Cranial nerves " Bells Palsy"

I was looking up cranial problems and I found out Bells palsy was caused from cranial nerve problems. I found this subject interesting b/c my profressor in the xray program was diagnosed with Bells palsy. He came to class one day and had slurred speech, droopy face on one side and his eye was watering uncontrollably. A time went on he gradually got better and better until one day he was back to normal. While researching I found out that Bell's palsy is caused when the nerve that controls the facial muscles becomes swollen or compressed. Over 40,000 americans are diagnosed with Bells palsy each year. I found my information from http://www.mayoclinic.com/
