Body type diagram

Here is a diagram I made for a lecture on body type/gender variations in my Anatomy class. The goal was to understand how skeletal, muscle, and fat can change to effect the silhouette of the figure. The silhouette, as a popular design element, is conditioned in a couple ways. One, from the inside out (natural anatomical qualities and their variety), and two, from the outside (class/societal structure can often determine habits and types of behaviors which cause for varied silhouettes).
