Skeletal muscles, attached to bones and tendons, help us move voluntarily and quickly. Cardiac muscles, found only in the heart, work involuntarily and at a moderate speed to keep our heart beating. Smooth muscles, found in hollow organs and blood vessels, work slowly and involuntarily to control functions like digestion and blood flow. Each muscle type has a unique cellular structure.
