Verified step by step guidance1
Understand the structure of the skin: The skin is composed of three primary layers—epidermis, dermis, and subcutaneous tissue (also referred to as the hypodermis). Each layer has distinct functions and characteristics.
Identify the outermost layer: The epidermis is the outermost layer of the skin. It acts as a protective barrier against environmental factors such as pathogens, UV radiation, and water loss.
Differentiate the layers: The dermis lies beneath the epidermis and contains connective tissue, blood vessels, nerves, and glands. The subcutaneous tissue (hypodermis) is the innermost layer, primarily composed of fat and connective tissue, providing insulation and cushioning.
Recall the correct terminology: The term 'epidermis' specifically refers to the outermost layer, while 'hypodermis' and 'subcutaneous tissue' are interchangeable terms for the innermost layer.
Confirm the answer: Based on the structure of the skin, the correct answer to the question is 'epidermis,' as it is the outermost layer.
