The primary function of ligaments in the musculoskeletal system is to connect bones to other bones, which is essential for maintaining the stability and integrity of the joints. Ligaments are fibrous connective tissues that provide support and allow for limited movement of the joints, preventing excessive motion that could lead to injuries. This connection is crucial for the overall function and biomechanics of the skeletal system, ensuring that the bones work together effectively during movement.

Understanding this role highlights the importance of ligaments in physical activities, as they help maintain joint stability under the stresses of everyday movement and athletic performance. The other options, such as providing muscle attachment points, forming cartilage, or aiding in blood circulation, pertain to different structures or functions within the musculoskeletal system and do not accurately describe the role of ligaments.
