Tendons are strong, flexible bands of tissue that connect muscles to bones. When a muscle contracts, it pulls on the tendon, which then moves the bone, allowing us to perform various activities like walking, running, or lifting. Tendons are made of collagen, which gives them their strength and durability. In our bodies, tendons play a crucial role in movement and stability. For example, the Achilles tendon connects the calf muscle to the heel bone, enabling us to push off the ground when we walk or run. Proper care and stretching can help keep tendons healthy and prevent injuries.
