Which of the following is a characteristic of tendons?

Tendons are connective tissues that primarily function to connect muscles to bones, enabling movement and supporting joint stability. One of their key characteristics is high mechanical strength, which allows them to withstand the tension generated during muscle contractions. This tensile strength is crucial for transferring forces from muscles to the skeletal system effectively.

The composition of tendons, primarily made up of collagen fibers, contributes to their strength and durability. The alignment of these fibers is oriented along the direction of tensile stress, further enhancing their ability to handle significant mechanical loads without being easily damaged. This high mechanical strength is essential for the functionality of tendons in various physical activities and sports, where they are subjected to considerable stress.

Other characteristics mentioned, such as high vascularization and high metabolic activity, are not typical of tendons. Tendons generally have a low vascular supply and metabolic rates compared to other tissues, which can affect their healing processes. Additionally, tendons connect muscles to bones, not bones to bones, which differentiates them from ligaments that perform that specific function.
