Dense regular connective tissue has parallel collagen fibers.

Dense regular connective tissue has parallel collagen fibers.

• A. Dense regular connective tissue has parallel collagen fibers
• B. Dense regular connective tissue has randomly oriented collagen fibers
• C. Dense regular connective tissue has many adipocytes
• D. Dense regular connective tissue is a type of cartilage

Answer: (A)

Collagen fibers in dense regular connective tissue are arranged in parallel bundles to resist tensile forces in a single direction. This organized alignment lets tendons and ligaments withstand pulling forces along the length of the tissue, with fibroblasts densely packing type I collagen to create strong, tightly aligned fibers and minimal ground substance. If fibers were randomly oriented, the tissue would function like dense irregular connective tissue, capable of withstanding stress from multiple directions. Having many adipocytes would point to adipose tissue, not dense regular connective tissue, and cartilage is a distinct tissue type with chondrocytes in lacunae within a different matrix.
