What is the primary function of ligaments?

1. Connect muscles to bones

2. Support organs

3. Hold bones together at joints

4. Protect the skin

The correct answer is: Hold bones together at joints

Ligaments serve a crucial role in the musculoskeletal system, primarily functioning to hold bones together at joints. They are fibrous connective tissues that connect one bone to another, providing stability and support to the joints. This stabilization is essential for maintaining proper alignment during movement, preventing excessive motion that could lead to injuries such as sprains and dislocations. While the other options describe important functions in the body, they do not pertain specifically to the role of ligaments. For instance, connecting muscles to bones refers to tendons, which are different connective tissues. Supporting organs is a function related more to the overall structural framework provided by different tissues and systems in the body, and protecting the skin is not associated with ligaments but rather with layers such as the epidermis and dermis. Understanding the specific role of ligaments helps clarify their importance in joint stability and overall musculoskeletal health.
