Ligaments primarily attach which two structures?

Ligaments are fibrous connective tissues that primarily serve the purpose of connecting bone to bone at joints. This connection helps stabilize joints and supports the overall integrity of the skeletal system. The arrangement and composition of ligaments allow them to withstand tensile forces while still permitting a degree of movement between the bones they connect, thereby playing a crucial role in joint stability and function.

The role of ligaments is distinctly separated from that of tendons, which connect muscles to bones, and their function should not be confused with other connective tissues. Understanding this definition clarifies why the attachment of bone to bone is the primary responsibility of ligaments in the musculoskeletal system.
