What is the role of ligaments in the body?

Ligaments play a crucial role in maintaining the stability and integrity of joints by connecting bone to bone. This connective tissue is primarily composed of dense, fibrous connective tissue, which provides both strength and flexibility. Ligaments are essential in preventing excessive movement at joints, thus protecting them from injuries caused by overextension or abnormal motions.

For example, in the knee joint, ligaments such as the anterior cruciate ligament (ACL) and posterior cruciate ligament (PCL) are critical in stabilizing the joint during movement. They ensure that the femur and tibia maintain their proper alignment while allowing appropriate ranges of motion essential for activities such as walking, running, and jumping.

While ligaments are indeed involved in supporting joint movement, their primary and most defining feature is the connection they create between bones, making them vital for joint stability.
