What are the essential differences and similarities between Skeletal and Smooth Muscle? How are Skeletal Muscle and Smooth Muscles different, and what is similar between Smooth Muscle and Skeletal Muscle? What are the functions of Skeletal muscles and Smooth muscles?
This video aims to provide comparisons between the essential introductory features of smooth and skeletal muscle contraction, with an introduction to actin and myosin myofilaments, sarcomeres, excitation-contraction coupling, cross-bridge cycling and cells, physiology of smooth muscle, what is smooth muscle and skeletal muscle, tropomyosin, troponin, calmodulin, the sliding-filament theory, why skeletal muscle is often more red in colour (many skeletal muscles have large stores of myoglobin and oxygen, providing that rich red colour when cut and exposed to the air), the appearance of smooth and skeletal muscle, the function of smooth and skeletal muscle, skeletal and smooth muscle structure, skeletal and smooth muscle fibers. Hopefully, all the essential things you'll need to learn as you start to understand the similarities and differences between skeletal and smooth muscle!
And all in ~4 minutes!
