An in class video describing how action potentials are generated in autorythmic cells and cardiac muscle cells of the heart. Discussion includes the initial conditions set up by the Na/K ATPase, the ion channels involved (in a general sense), and the overall shape of the action potential. This video is intended for pre-allied health students in a community college anatomy and physiology course. A scan of my hand-drawn notes that I use to create this lesson can be found at http://www.kirkwood.edu/pdf/uploaded/695/handrawn_cardiac_action_potentials.pdf
