What is the primary function of ligaments in the body?

The primary function of ligaments is to connect bone to bone. Ligaments are dense, fibrous connective tissues that provide support and stability to joints by binding the ends of bones together. This connection helps to limit excessive movement and provides structural integrity to the skeletal system. By maintaining proper alignment between bones, ligaments play a crucial role in ensuring joint stability during both static positions and dynamic activities, making them vital for overall musculoskeletal function.

Other options describe different types of connective structures: tendons connect muscle to bone, nerves transmit signals between nerve cells, and the connection of skin to muscle typically involves fascia and does not involve ligaments. Understanding these distinctions helps clarify the unique role of ligaments in the body.
