Cardiomyocytes are specialized muscle cells found in the heart. They are responsible for the contraction and relaxation of the heart, enabling it to pump blood throughout the body. These cells are unique because they can generate electrical impulses, which coordinate the heartbeat and ensure efficient blood flow. Cardiomyocytes are characterized by their striated appearance and are interconnected through structures called intercalated discs. This connectivity allows for synchronized contractions, which are essential for maintaining a steady heart rhythm. Damage to cardiomyocytes, such as from a heart attack, can impair heart function and lead to serious health issues.
