What are the three layers of the skin?

The skin is composed of three distinct layers: the epidermis, the dermis, and the hypodermis.

The epidermis is the outermost layer, serving as a protective barrier against environmental factors such as pathogens and UV radiation. It is primarily made up of keratinized cells, which help to prevent water loss and contribute to the skin's overall integrity.

Beneath the epidermis lies the dermis, which is much thicker and contains a rich supply of blood vessels, nerves, and connective tissue. This layer provides structural support and elasticity to the skin. It also houses important structures like hair follicles and sweat glands.

The hypodermis, or subcutaneous layer, is the deepest layer of the skin and primarily consists of fat and connective tissue. This layer acts as an insulator, helping to regulate body temperature, and serves as a cushion to protect underlying muscles and bones.

Together, these layers work in concert to protect the body, regulate temperature, and provide sensory information, making the correct answer highlighting the epidermis, dermis, and hypodermis the most accurate depiction of skin anatomy.
