Which statement best describes the arrangement of collagen fibers in dense regular connective tissue?

• A. Random mesh
• B. Circular rings
• C. Absent
• D. Parallel bundles

Answer: (D)

Collagen fibers in dense regular connective tissue are organized into parallel bundles that run in the same direction. This specific alignment provides great tensile strength along that axis, which is essential for structures like tendons and ligaments that routinely experience pulling forces in one direction. When fibers are parallel, the tissue can efficiently transmit muscle force to bone or stabilize joints in a single direction. If the fibers were arranged as a random mesh, you’d be dealing with dense irregular connective tissue, which resists forces from many directions rather than just one. If fibers were absent, the tissue wouldn’t have the strength characteristic of dense connective tissues. Circular rings do not describe the typical organization of dense regular connective tissue, as its hallmark is this orderly parallel arrangement rather than concentric rings.
