Brief Answer: there are web images Detailed Answer: Hi Unfortunately I am not able to attach images but if you place upper limb myotomes into google search engine and then click on images you will be able to find an image. In addition if you put grants atlas upper limb myotomes into the search engine you would also get images and ideas of the movements of the muscles. Please feel free to ask anything else
