Subcutaneous tissue
Verified step by step guidance1
Step 1: Understand the structure of the skin, which is composed of three main layers: the epidermis (outermost layer), dermis (middle layer), and hypodermis (innermost layer).
Step 2: Recall that the epidermis is the outermost layer of the skin and serves as a protective barrier against environmental factors such as pathogens, UV radiation, and water loss.
Step 3: Differentiate between the layers: the dermis contains connective tissue, blood vessels, and nerves, while the hypodermis (also called subcutaneous tissue) is primarily composed of fat and connective tissue for insulation and cushioning.
Step 4: Eliminate incorrect options by identifying that the dermis, hypodermis, and subcutaneous tissue are not the outermost layer of the skin.
Step 5: Conclude that the correct answer is the epidermis, as it is the outermost layer of the skin.
