The dermis is divided into two sublayers. Which are they?

• A. Papillary and Reticular
• B. Epidermis and Dermis
• C. Stratum Corneum and Stratum Lucidum
• D. Hypodermis and Dermis

Answer: (A)

Two layers make up the dermis: the papillary layer and the reticular layer. The papillary layer sits just beneath the epidermis and is composed of loose connective tissue. It contains dermal papillae that interlock with epidermal ridges, increasing surface area for nutrient exchange and housing capillaries and small sensory receptors. The reticular layer lies deeper and is thicker, made of dense irregular connective tissue rich in collagen and elastin fibers, which gives the skin strength and elasticity. It also contains hair follicles, sweat and sebaceous glands, nerves, and most of the dermal blood vessels.

The other options refer to structures outside this dermal subdivision: the epidermis is the outer protective layer with layers like the stratum corneum and stratum lucidum, and the hypodermis is the subcutaneous tissue beneath the dermis.
