In addition to spontaneous stimulation, smooth muscle can be stimulated by pacesetter cells that are similar to pacemaker cells and trigger waves of action potentials in smooth muscle. Smooth muscle can also be stimulated by the autonomic nervous system or hormones.

Web28 de set. de 2024 · Smooth muscle is different in structure to other types of muscle. It doesn’t have the organised sarcomeres like cardiac and skeletal (meaning it is not striated), and does not have T tubules in the sarcolemma. The actin-myosin interactions that occur in smooth muscle are slow and sustained, with a low ATP demand. Web34. Muscular Levels of Organization. The force generation required for skeletal muscle function occurs at the molecular level. You can develop a better understanding of the properties of cells and tissues by studying the molecular mechanisms common to the cells involved: Molecular level — actin and myosin. 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) gqeberha: the empire full episodes

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.
