    First: Very interesting graphic on the sliding filament mechanism! It made it very easy to visualize a difficult concept. I learn better by breaking things down into a step by step process, the graphic did that very well. Second: I LOVE the McGraw Hill videos! They explain complicated topics in a way that can be understood, and this video did not disappoint. Last: What a great ides to have a short quiz and review at the end. I think your segment would be a great addition to an anatomy class 🙂
