You think that your comments about me causing only harm and posting BS did not hurt me? Maybe now you get the feeling.
Alright, I am not going to be an idiot (though I was said to be).
Contraction fasciculations result from enlarged motor units, i.e. after denervation, the healthy nerves supply also the bundles that lost innervation. But then of course, activation of one unit causes activation of these "additional" units too.
But this is not observed in the tongue, I can assure you (when it is, you could hardly talk). Tongue displays fasciculatory movements when not held still, these are not contraction fasciculations. This is why it is so important to hold it absolutely still during the exam, because of the possible confusion.
Added from my smartphone:
The fact that your fasciculations disappear once your tongue rests proves there is no nuclear or infranucleal lesion. If ithere was, your tongue would ripple when rested. It is entirely normal for the tongue to fasciculate when slightly flexed - tongue is not a muscle, there are at total 8 muscles, many interlacing each other. Imagine you want to keep balanance holding 8 dishes: some will tremble if you move!
Despite what you wrote about me, I do hate seeing people in anxiety and I hope this will finally help you understand. When my wife sticks out her tongue just a few millimeters, I swear it looks like a bag of worms. But it is silent when resting and that is what you are so interested in.
