The strength layer of the skin is known as the _____.

• A. Dermis
• B. Reticulum
• C. Epidermis
• D. Hypodermis

Answer: (A)

The strength of the skin comes from the dermis. This middle layer is made of dense irregular connective tissue rich in collagen fibers, which give skin its tensile strength and resistance to tearing. Elastic fibers add resilience, helping the skin snap back after being stretched. The dermis also contains hair follicles, glands, nerves, and blood vessels, but its strong collagen network is what mainly provides structural integrity. Within the dermis, the deeper reticular layer is especially dense and contributes most to strength, while the superficial papillary layer is looser and helps with nourishment and grip. The outer epidermis is a protective barrier, and the underlying hypodermis stores fat and cushions the body.
