What is the primary function of ligaments in the body?

The primary function of ligaments in the body is to support and stabilize joints. Ligaments are fibrous connective tissues that connect bones to other bones at joints, providing both stability and support during movement. They play a crucial role in maintaining the integrity of joints by preventing excessive movements that could lead to injuries. By connecting bones, ligaments help ensure that the structures of the skeleton remain aligned and can effectively bear weight and withstand stress during various physical activities.

In contrast, ligaments do not connect muscle to bone, which is a function specific to tendons. Additionally, ligaments do not directly produce red blood cells; that function is primarily associated with the bone marrow. Ligaments also do not store calcium; this role is primarily managed by bones themselves. Thus, the correct answer accurately reflects the essential role ligaments play in joint function and overall musculoskeletal health.
