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. WebThe type of muscle corresponds with their function. Striated muscles are better suited for bursts of expansion and contraction, while smooth muscles are better for handling smooth, sustained contractions. If the wrong type of muscle was in a certain part of the body, it would be very ineffective. ( 4 votes)

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. WebSmooth muscle contains spindle-shaped cells 50 to 250 μm in length by 5 to 10 μm in diameter. These cells possess a single, central nucleus. Surrounding the nucleus and throughout most of the cytoplasm are the thick ( myosin) and thin ( actin) filaments. Tiny projections that originate from the myosin filament are believed to be cross bridges.
