The following is a great tutorial on the Cardiac Conduction system. Pretty easy to understand. If you click on "view all animations" it will take you to a large compilation of cardiac tutorials, as well as a variety of other types of medical animations.

MUSCLES

This is a great site for making flashcards of the cat muscles. It has virtually every photo and label you could imagine. Great resource if you havent' found it already!

Found a couple more websites that have good information on them. The following is one from Saddleback that a professor posted. It is set up as I imagine the lab practical will be. Check it out:

The following is a good site to identify the muscles on a skeleton. It shows origin, insertion and the action. The one below that shows the dissected cat, the human muscle it correlates too, all the above information plus a Quicktime video of the movement.
