Join the Amoeba Sisters as they explore different muscle tissues and then focus on the sliding filament theory in skeletal muscle! This video also briefly talks about muscle naming and some vocabulary (such as agonists and antagonists) before focusing on the sliding filament model. The video also mentions the general roles of tropomyosin and troponin.
