Early in my search I came across a pretty useful anatomy tool. It is 3D anatomy software that allows you to add or remove systems of the body including the nervous system and muscles.
With a little searching you can easily find out what muscles are innervated by the particular nerve(s) that is in question and type it in the search box of the software. You can also add or subtract individual nerves, muscles, organs, etc. as well as highlight them, zoom in, rotate, etc.
The site is called
Visible Body | 3D Human Anatomy and is free.
