kashmala, u r right, tonguue is supposd to prutrude towrds the side of lesion(CN XII)
but this pt is having s/s that he can not protrude his tongue to the left, so where is the lesion??? it means he has right side XII nerve injury. I post this q again simply because FA is wrong on this q and I was reviewing FA today so I want to bring it up one more time
