A major problem with my idea that my tongue is right side dominated is that I can move it normally and that I feel the left side. My tongue does not deviate but would if there was a lesion in either the innervation or the brain. It leaves me to conclude that there is something in the tongue structure that allows it to be dominated by one side though it needs the other side to be innevated normally with the abilty to contract and relax.
Elephant trunks, monkey tails seem to have those characteristics and when they specialize with complex tasks one side of the brain seems to dominate.
