Verified step by step guidance1
Understand that the skin is composed of three primary layers: the Epidermis (outermost), Dermis (middle), and Hypodermis (innermost). These layers are organized based on their anatomical position and function.
The Epidermis is the outermost layer, primarily responsible for protection. It is composed of stratified squamous epithelial cells and lacks blood vessels.
The Dermis lies beneath the Epidermis and contains connective tissue, blood vessels, nerve endings, sweat glands, and hair follicles. It provides structural support and elasticity to the skin.
The Hypodermis, also known as the subcutaneous layer, is the innermost layer. It consists of adipose tissue and connective tissue, serving as insulation and cushioning for the body.
To answer the question, identify the correct order of the layers from outermost to innermost: Epidermis, Dermis, Hypodermis.
