Question

Describe the unique anatomical features of cardiac muscle. What role does the unique structure of cardiac muscle play in its function

Answer 1

Answer:

The cardiac muscle is made up of branched muscle cells, which have 1 or 2 nuclei and which the contact area between the heart fibers gives rise to specialized regions at the level of the plasma membrane called intercalary discs. The intercalary discs unite the cardiac muscle cells with each other, which provides greater adhesion to the tissue and intervenes in the rapid communication between cells. This allows its simultaneous contraction and the production of the beat.

Explanation:

The intercalary discs are the union systems that associate the cardiac muscle cells to form the myocardial fibers, the cardiac muscle is the muscle tissue of mixed components, which is located exclusively in the walls of the heart. For this reason, it has the function of generating the necessary contractions for the blood to reach all parts of the body.The intercalary discs are a special type of intercellular junction, a gap that guarantees electrical communication between these cells; and on the other hand, it provides places of adhesion and anchorage of one cell with another. The intercalary discs provide the structural foundation that allows the heart to behave as a functional syncytium.
