How does the ligament allow the bones in joints move smoothly over each other?

Ligaments are strong, flexible bands of connective tissue that connect bones at joints, providing stability while allowing a certain range of motion. They help maintain the alignment of the bones, reducing the risk of dislocation and injury. Additionally, synovial fluid, found in the joint capsule, lubricates the surfaces of the bones, facilitating smooth movement as the ligaments support and guide the bones during motion. Together, these structures ensure that bones can glide over one another without friction or damage.
