Heart muscle cells

Heart muscle cells, called cardiomyocytes, are specialized cells that make up the heart's muscular wall. They are designed to contract rhythmically and forcefully to pump blood throughout the body. These cells are unique because they can generate electrical signals and work together in coordinated networks, allowing the heart to beat efficiently. They have a rich supply of mitochondria, providing energy for continuous activity. Unlike most other cells, heart muscle cells have limited ability to regenerate after damage, which is why heart injuries like heart attacks can have lasting effects. Their proper function is essential for maintaining healthy circulation.
