__** Muscles **__ Sites on muscles and muscle tissue, etc. are literally endless. Here are just a few to get started, but of course you can search just like I can. A good place to start is the first one. Remember that you are listing your sources and they need to be credible such as universities, government sites, reputable journals and newspapers. Although some others are not selling anything except ads, for example: about.com, double check the information with another source as many of these kinds of sites can be edited by anyone. Those of you looking for information on exercise and muscle development need to be careful of sites promoting a product. [|http://health.howstuffworks.com/muscle.htm] - great site at your level even to the biochemical aspects of contraction with animation

http://science.nationalgeographic.com/science/health-and-human-body/human-body/heart-article.html? - animated basics of the heart

http://biology.about.com/od/anatomy/a/aa022808a.htm - nice stained slide of heart muscle tissue
