Integumentary system includes which components?

• A. Epidermis only
• B. Dermis only
• C. Hypodermis only
• D. Epidermis, Dermis, and Hypodermis, along with glands, hair, and nails

Answer: (D)

The integumentary system is the skin plus its supporting layers and all the structures that arise from it. The skin has three layers: the outer epidermis that provides a protective barrier, the middle dermis that gives strength and houses nerves, blood vessels, and glands, and the deeper hypodermis (subcutaneous tissue) that stores fat, cushions, and helps insulate. In addition to these layers, the system includes accessory structures such as glands (sebaceous and sweat glands), hair follicles with hair, and nails. These components work together to protect, regulate temperature, sense the environment, and assist with everyday functions. So, the most complete description is epidermis, dermis, and hypodermis, along with glands, hair, and nails.
