No, ligaments are not hard. They are strong and flexible.
Ligaments are crucial connective tissues in the body, primarily composed of collagen fibers. These fibers give ligaments their strength and resilience, allowing them to withstand pulling and compressive forces. However, the arrangement and composition of collagen also contribute to their flexibility, enabling joints to move within a normal range of motion. Ligaments are more accurately described as being tough and resilient rather than hard.
Think of them like strong, flexible ropes that connect bones together, allowing for movement but also providing stability. While they're not soft like muscle, they aren't rigid like bone either. Their main function is to prevent excessive or abnormal joint movement, so they need a degree of "give."
