a highly detailed cross-section of human skeletal muscle fibers, shown in vibrant red and pink tones, with visible striations and realistic texture. Glowing arrows and animated icons represent active metabolic processes—such as glucose uptake, fat oxidation, and ATP production—occurring within the muscle tissue. Surrounding the muscle, floating symbols for mitochondria and energy highlight its metabolic activity. The background is clean and clinical, with subtle labels and infographics explaining that muscle is a metabolically active tissue. The overall style is modern, scientific, and visually engaging, suitable for educational or medical use. in italianoemoji
