he instructional DVDs are actual lectures, many of which were done as part of my regular classes. Demonstration tapes are not lectures but demonstrations with the camera following every action. These demonstrations are exactly what I give the students as were many of the drawings on the drawing pages of this web site. The DVD's are higher resolution than the video tapes and include extra features such as: Drawings by Glenn Vilppu and Models to draw from. Extra features will vary from DVD to DVD Neck Anatomy - Contains lecture, drawing, models to draw from, and demonstration. Upper Torso Anatomy - Contains lecture, drawing, models to draw from, and demonstration. Pelvis Anatomy - Contains lecture, drawing, models to draw from, and demonstration.
