What is a primary function of a tendon?

A primary function of a tendon is to provide connective flexibility, which is essential for the proper functioning of muscles and joints. Tendons are tough, fibrous connective tissues that attach muscles to bones, allowing for the transfer of force from muscle contractions to bone movement. This connection enables the flexibility and range of motion necessary for various physical activities.

While tendons do contribute to stability in a joint, their main role isn't directly about flexibility alone but more about facilitating movement through flexible attachment points. This is why the concept of connective flexibility aligns closely with the primary function of tendons in facilitating movement and enabling muscles to exert forces on bones effectively during activities.

The other options do not accurately describe the primary function of tendons. Protecting tissues, supporting bone density, or facilitating verbal communication are roles associated with other types of tissues or structures in the body, rather than the primary function of tendons.
