Which two layers comprise the dermis?

• A. Reticular, Papillary
• B. Epidermis, Hypodermis
• C. Papillary, Reticular
• D. Elastic, Collagen

Answer: (C)

The dermis has two distinct layers: the papillary dermis and the reticular dermis. The papillary dermis is the superficial layer just beneath the epidermis and is made of loose connective tissue with tiny projections called dermal papillae that interlock with the epidermal ridges, helping to nourish the epidermis and house small blood vessels and nerve endings. The reticular dermis lies deeper and is composed of dense irregular connective tissue rich in collagen and elastin fibers, which gives the skin strength, elasticity, and resistance to tearing; this layer also contains most of the skin’s structures, such as hair follicles, sweat and sebaceous glands, nerves, and larger blood vessels. The epidermis sits above this and is separate, while the hypodermis (subcutaneous tissue) lies beneath the dermis and is not part of it. Fibers like collagen and elastin are components within the dermis, not separate layers.
