Final answer:
Dense regular connective tissue closely packs collagen fibers in parallel, enhancing tensile strength and resistance to stretching. Examples include tendons, ligaments, and elastic ligaments in the vocal folds and spinal column.
Step-by-step explanation:
Dense regular connective tissue is characterized by collagenous fibers packed into parallel bundles. This particular arrangement provides greater resistance to stretching and enhances tensile strength in one direction. Examples of structures composed of this tissue include tendons, which connect muscles to bones, and ligaments, which connect bones to bones. However, it is noteworthy that in ligaments, the fibers are not completely parallel.
Dense regular connective tissue can also be found in the form of elastic ligaments. These contain elastin fibers in addition to collagen fibers, which enable the ligaments to return to their original length after being stretched. Examples include the elastic ligaments in the vocal folds and those located between the vertebrae in the vertebral column.
