All muscle cells contain striations..

Assignment #5- Chapters 9 & 10. Get a hint. Which of the following statements is correct? Smooth and Skeletal muscle fibers are involuntary and striated. Cardiac muscle fibers are short and voluntary. Smooth muscle fibers are spindle shaped and found in hollow organs.Compared to skeletal muscle, smooth muscle cells are small. They are spindle shaped and have no striations. Instead, they have bundles of thin and thick filaments. Looking closer at skeletal muscle. All skeletal muscle fibres are not the same. They differ in structure and function, for example, in the speed they can contract.The muscles all begin the actual process of contracting (shortening) when a protein called actin is pulled by a protein called myosin. This occurs in striated muscle (skeletal and cardiac) after specific binding sites on the actin have been exposed in response to the interaction between calcium ions (Ca ++) and proteins (troponin and tropomyosin) that "shield" the actin-binding sites.Cardiac muscle is able to contract and relax, unlike skeletal muscles which only contract. This means that cardiac tissue will have far more irregular shapes than skeletal muscles. Cardiac muscle cells contain T tubules that connect to the sarcoplasmic reticulum which stores the calcium ions needed for the contraction of the cell.6/24/2019. View full document.
