Which tissue type forms the dermis?

Which tissue type forms the dermis?

• A. Dense regular connective tissue
• B. Dense irregular connective tissue
• C. Elastic connective tissue
• D. Loose connective tissue

Answer: (B)

The dermis is primarily dense irregular connective tissue, which allows collagen fibers to be arranged in many directions. This multi-directional fiber arrangement gives skin the strength and durability to withstand stress from all angles. Dense regular connective tissue, with fibers aligned in one direction, would resist force only in a single direction, making it unsuitable for skin. Loose connective tissue forms the superficial papillary layer and provides vascular support, but the bulk of the dermis is dense irregular connective tissue. Elastic connective tissue contributes elasticity but is not the main tissue type of the dermis.
