Allie just reminded me of something that might help anyone who's taking Anatomy.
My teacher (who was absolutely excellent, by the way, and literally dedicated her life to teaching Anatomy) made YouTube videos of models (muscles, the heart, layers of skin, etc.) where she took a model and pointed out everything on it and what it was and how it worked. It was a LIFE SAVER and I know people who weren't even in her class used those videos and it saved them, too.
Go to www.youtube.com
and type in "Anatomy Dixon" and you'll get a bunch of videos including the Lymphatic System, a nerve cell, the heart, brain, spinal cord, etc.
They REALLY helped me and I hope they help everyone else!
