In dense regular connective tissue, collagen fibers are organized how, and which cells are commonly interspersed?

• A. Chondroblasts
• B. Fibroblasts
• C. Adipocytes
• D. Osteocytes

Answer: (B)

The main idea is how dense regular connective tissue is built to handle force in one direction. In this tissue, collagen fibers are arranged in tightly packed, parallel bundles, all aligned with the direction of pull to give strength along that single axis. The cells that are commonly interspersed among these fibers are fibroblasts, the producers of collagen and other components of the extracellular matrix. They’re typically spindle-shaped and run between the fiber bundles, actively synthesizing and organizing the collagen fibers. Chondroblasts would indicate cartilage formation, adipocytes are fat-storing cells, and osteocytes are bone cells, so they don’t describe the cellular makeup of dense regular connective tissue.
