WebAbout half of your body’s weight is muscle. In the muscular system, muscle tissue is categorized into three distinct types: skeletal, cardiac, and smooth. Each type of muscle tissue in the human body has a unique structure and a specific role. Skeletal muscle moves bones and other structures. Cardiac muscle contracts the heart to pump blood. WebSmooth muscle contraction, induced by acetylcholine through the muscarinic M3 receptor, starts with the release of Ca2+ from intracellular stores. Ca 2+ binds calmodulin that is complexed with myosin light chain kinase. This leads to activation of the kinase and subsequent phosphorylation of regulatory myosin light-chain at serine-19. imdb convicts
