Full Transcript

Join the Amoeba Sisters a they explore different muscle tissues and then focus on the sliding filament theory in skeletal muscle! This video also briefly talks about muscle naming, some vocabulary (such as agonists and antagonists) before focusing on the sliding filament model. Video also mentions general roles of tropomyosin and troponin. --------------------------------------------------------- Table of Contents: 00:00 Intro 0:39 Muscle Tissue Types 1:58 Muscle Characteristics 2:33 Skeletal Muscle Naming and Arrangement 3:26 Actin Myosin and Sarcomere 4:32 Sliding Filament Model 6:55 Tropomyosin an Troponin --------------------------------------------------------- Factual References: Betts, J.
