Dense regular connective tissue is primarily composed of what and where is it found?

• A. Collagen fibers in parallel; tendons and ligaments
• B. Reticular fibers in a mesh; lymphoid organs
• C. Collagen fibers in a net; dermis
• D. Elastic fibers in parallel; arteries

Answer: (A)

Dense regular connective tissue features collagen fibers densely packed and arranged in parallel, giving high tensile strength in a single direction. This orderly alignment lets tendons transmit muscle force to bone and ligaments stabilize joints by resisting pulling forces along a specific axis. The main component is type I collagen produced by fibroblasts, with the fibers running in the same direction to coordinate force. This is why it’s found in tendons and ligaments. By contrast, reticular fibers form a mesh in reticular connective tissue that supports lymphoid organs, the dermis contains dense irregular connective tissue with fibers arranged in many directions to handle forces from multiple angles, and arteries rely on elastic fibers organized for stretch and recoil rather than a single, parallel collagen arrangement.
