Which is the loose connective tissue in the hypodermis that contains collagen?

• A. Adipose tissue
• B. Elastic tissue
• C. Areolar tissue
• D. Reticular tissue

Answer: (C)

The tissue described is areolar tissue. In the hypodermis (subcutaneous layer), areolar tissue is a loose connective tissue that contains collagen and elastic fibers within a gel-like ground substance. It provides flexibility and support between the dermis and deeper structures, and its loose arrangement allows nerves, blood vessels, and fat to be accommodated. Adipose tissue is present in the hypodermis mainly for fat storage and insulation, not as the loose connective tissue characterized by a network of collagen fibers. Elastic tissue is focused on elasticity, and reticular tissue forms a supportive mesh in organs, so they don’t match the description as well. Hence, areolar tissue best fits the role.
