I have found that Michelangelo Buonarroti have created sculpture called Rebellious slave. The sculpture is placed in museum Louvre in Paris. It greatly shows the shapes of muscles of left arm, especially from back view. The arm is placed and rotates in position of Takate kote, hence here is some guide-line for those learning about muscles structure for safety reasons. http://www.youtube.com/watch?v=h44bnIGogu8
Anyway it was impossible to find any image from back view on net. So if you go to Louvre, please take some image :-) of the Rebellious slave from back.
