Cardiac muscle fibres resemble both straited smooth muscle fibres as it is uninucleated (like smooth muscle fibres) and have dark and light bands known as straitions (like straited muscle fibres).Moreover it is comtrolled by both central autonomous nervous systems. So in brief, Cardiac muscles resemble skeletal muscles in the following ways: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.The conducting system is in contact with the contractile cardiac myocytes via gap junctions. These cells are what initiate the heartbeat and help spread the impulse (action potential) rapidly through the heart. The self-excitable, autorhythmic, myocytes have the 2 important roles: 1. Formation of the conduction system of the heart.Study with Quizlet and memorize flashcards containing terms like What characteristics describe both skeletal and cardiac muscle?
