From, through, to

[nyggus]

These worms inhabit different parts of a dragon, from its claws through paws, trunk and wings to three heads.

Disregarding the obvious nonsense of the above sentence and treating it just as an example of the structure, could you help me with the following?
1. I have problems with punctuation: should I put a comma before the through and the to?
2. Is up to better here than to?

Thanks,
Nyggus

Hello, I don´t recommend to use commas in front of "through" and "to" but I suggest to put one in front of "and" (paws, trunk, and wings).
Regarding "to" and "up to" - I think "up to" is more expressive and means more than "to", something like "all the body to".
