The minor chakras - what do they really do?

Out of all the Chakra related information on the internet and in some books, the minor Chakras seem to be either mysterious or not as important as it's neighbors. Even some of the drawings I've seen are pretty weak when they are represented. One had them like look like moles on the body.

From my observations in doing energy work, they are important, and still mysterious. They do seem to be connected to the heart chakra and they seem to be tools that the heart chakra uses, especially from an energy worker point of view. The minor chakras in the hands seem to be also connected to either a minor eye chakra or the big boy third eye chakra. They even might be part of the energetic evolution that is taking place in humans, which could be part of 2012 or it might not. Either way they are deserving of our attention and respect.
