I've heard plenty of talk about this amongst some of the pressure point and some talk of polarity but nothing I can recall being of any use. Within TCM there are divisions of yin and yang within the body... there is a table on this page and its been a while since I did my exams on this stuff so I'm a bit hazy now.

Within tai chi that is a lot of emphasis placed on yin and yang shapes within the body and in the arms. For example aun is yang and peng is yin and these principles can be explored extensively in the push hands lessons from the section of Yang Cheng Fu's long form called grasp sparrows tail.
