Tendon structure is primarily composed of which component?

Tendons are built to transmit muscle force with maximal tensile strength, so their primary component is Type I collagen organized into long, parallel fibers that group into fascicles. This arrangement gives the tissue great strength along the line of pull, which is essential for efficient force transfer from muscle to bone. Type I collagen is the dominant collagen in mature tendon, while Type III appears more during development and healing (as a less organized scaffold) and is not the main load-bearing component. Elastic fibers exist but do not provide the primary tensile strength, and bone tissue would not be part of tendon itself. Thus, Type I collagen organized into fascicles best describes tendon structure.
