Tendons are strong, flexible bands of tissue that connect muscles to bones. They play a crucial role in movement by transmitting the force generated by muscles to the skeleton, allowing us to perform activities like walking, running, and lifting. Tendons are made of collagen, which gives them their strength and durability. When a muscle contracts, it pulls on the tendon, which then pulls on the bone, creating movement at the joint. Injuries to tendons, such as tendonitis or tendon tears, can cause pain and limit mobility. Proper care, including stretching and strengthening exercises, can help keep tendons healthy and functioning well.
