This question is based on another question that I asked last year: How to Give an Ordinary Man Vampire Strength
That question was on the basis on one overlooked trait of Bram Stoker's Count Dracula, that he possessed the strength of twenty men. In the only answer I got was this one crucial sample:
A chimp is two to five times stronger than a human per unit weight, but doesn't have the same level of fine motor control.
In other words, while a chimpanzee does have enough strength to be considered "superhuman", it lacks the finer nuances of dexterity needed for the finer things of life, like holding a pencil long enough to write an old-fashioned essay on the meaning of life. That is the price to pay for having denser nerve fibers, but this has left me asking: Is this sort of extra nerve fiber density monolithic among the entire body? Or can certain parts of the body have differences in nerve fiber densities?
In this scenario, the nerve density of a human hand and fingers are the same, but the nerve fibers on the arms are far denser. Is this sort of differentiation possible, much less feasible?
