Which layer of the skin contains collagen fibers, elastin, and sensory receptors, providing strength and elasticity?

• A. Dermis
• B. Stratum corneum
• C. Epidermis
• D. Hypodermis

Answer: (A)

The dermis is the layer you’re looking for. It’s a thick, fibrous connective tissue layer rich in collagen fibers that give the skin its tensile strength and elastin fibers that allow it to stretch and snap back. This combination is what keeps skin strong yet flexible, especially as the body moves. The dermis also houses the sensory receptors that let you feel touch, pressure, and other sensations, along with hair follicles, glands, and a network of blood vessels. In contrast, the epidermis is the outer protective barrier made mainly of keratinocytes, with the outermost sublayer called the stratum corneum being composed of dead cells, and the hypodermis beneath containing fat that provides insulation and padding rather than elasticity.
