This product is a no frills PowerPoint covering skeletal muscle microscopic anatomy and physiology. It is content heavy with not many pictures and graphics. The PowerPoint includes slides that have students visualize certain aspects of muscle structure and draw certain biomechanics of molecular movement. I found breaking up lectures with students doing a task like drawing processes or using items to make a model very helpful in their understanding of the material. This product would also be great for instructors to printout and make their own notes to prepare for lectures. The product could be used in anatomy and physiology, health science, nursing, or AP Biology. There are 56 slides in this product.
