Answer:
Cardiac muscle (also called heart muscle or myocardium) is one of three types of vertebrate muscle, with the other two being skeletal muscle and smooth muscle. It is involuntary, striated muscle that constitutes the main tissue of the wall of the heart. The cardiac muscle (myocardium) forms a thick middle layer between the outer layer of the heart wall (the pericardium) and the inner layer (the endocardium), with blood supplied via the coronary circulation. It is composed of individual cardiac muscle cells joined together by intercalated discs, and encased by collagen fibers and other substances that form the extracellular matrix.
Answer:
Our Heart contains cardiac muscles.
Explanation:
1)Cardiac muscle, composed of the contractile cells of the heart, has a striated appearance due to alternating thick and thin filaments composed of myosin and actin.
2)Actin and myosin are contractile protein filaments, with actin making up thin filaments, and myosin contributing to thick filaments. Together, they are considered myofibrils.
3)Myosin and actin adenosine triphosphate ( ATP ) binding allows for muscle contraction. It is regulated by action potentials and calcium concentrations.
4)Adherens junctions, gap junctions, and desmosomes are intercalated discs that connect cardiac muscle cells. Gap junctions specifically allow for the transmission of action potentials within cells.
