The dermis is primarily composed of which connective tissue type?

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

Answer: (B)

The dermis is built mainly from dense irregular connective tissue, whose collagen fibers form thick bundles oriented in many directions. This arrangement provides strength and resistance to pulling forces from multiple directions, which is essential for skin that must withstand stretching and twisting. Dense regular connective tissue, by contrast, has parallel fibers and is found in tendons and ligaments for unidirectional tension. Elastic connective tissue includes a lot of elastic fibers for recoil, common in arterial walls and certain ligaments. Loose areolar connective tissue is looser and more space-filled, typical of the papillary dermis but not the primary mass of the dermis. So the correct description is dense irregular connective tissue.
