Ligaments are strong, flexible bands of connective tissue that connect bones to other bones at joints. They help stabilize and support the joints, allowing for movement while preventing excessive motion that could lead to injuries. For example, the ACL (anterior cruciate ligament) in the knee is crucial for maintaining stability during activities like running and jumping. In addition to providing support, ligaments also play a role in proprioception, which is the body's ability to sense its position in space. This helps us maintain balance and coordination during physical activities. Overall, ligaments are essential for joint function and overall mobility.
