Cardiac Muscle Fibers
Cardiac muscle fibers are specialized muscle cells that make up the heart. They are uniquely structured to work together, contracting rhythmically and efficiently to pump blood throughout the body. These fibers are interconnected, allowing electrical signals to travel quickly and synchronize heartbeats. Unlike other muscles, cardiac fibers are involuntary, meaning the heart beats automatically without needing conscious effort. Their design provides strength, elasticity, and the ability to sustain continuous activity, essential for maintaining healthy circulation and overall bodily function.
