Heart Muscle Cell (Cardiomyocyte)

Heart muscle cells, called cardiomyocytes, are specialized cells that make up the walls of the heart. Their primary role is to contract rhythmically, pushing blood throughout the body. These cells are unique because they can automatically generate electrical signals, coordinating the heartbeat, and are highly resistant to fatigue. Cardiomyocytes are rich in mitochondria, providing the energy needed for continuous activity. They are interconnected by structures called intercalated discs, enabling them to work together seamlessly for efficient and synchronized heart contractions essential for maintaining circulation and overall health.
