In contrast, smooth muscle cells are not striated but rather consist of dense bodies and intermediate filaments.

Cardiac muscle contains a great many mitochondria, which produce ATP for energy. This helps the heart resist fatigue. Contractions of cardiac muscle are involuntary, like those of smooth muscle. Cardiac muscle, like skeletal muscle, is arranged in bundles, so it appears striated, or striped.Cardiac muscle fibers are long cylindrical cells with one or two nuclei. The nuclei are centrally situated like that of smooth muscle. Cardiac muscle sarcoplasm has a great amount of mitochondria to meet the energy demands. Similar to the skeletal muscle, cardiac muscle cells have an invaginating network of T-tubules and sarcoplasmic reticulum.

Jul 30, 2023 · Introduction. Cardiac muscle also called the myocardium, is one of three major categories of muscles found within the human body, along with smooth muscle and skeletal muscle. Cardiac muscle, like skeletal muscle, is made up of sarcomeres that allow for contractility. However, unlike skeletal muscle, cardiac muscle is under involuntary control. skeletal muscle.

What are 5 characteristics of skeletal muscle. attached to bone. provides movement/support.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.Vertebrates possess two types of striated muscle: cardiac and skeletal.
