Actually even in Loomis Figure drawing book mentioned by Schwing the "basic manneqin" is a simplified skeleton. I think the reason is that for most people muscles are more fun. I like how Proko calms down his audience in Anatomy lessons promising that the muscles are going to be very soon, just a bit more bones :) But I would not be so sure that Schwing missed this part. Skeletal structure also something one can repeatedly return to if not memorised well and if one realises there's some fundamental problem with one's figure drawings.
