Light back becoming narrower. To address a common problem of teaching the sliding filament theory that is students have difficulty in visualizing how the component proteins of the sarcomere differ how they organize themselves into a single working unit and how they function in relation to each other we have devised a simple model with inexpensive materials to be built by students in the fourth year of an.
