1. Epidermis. This outer (superficial) layer of skin, composed of keratinized stratified squamous epithelium, derives from embryonic surface ectoderm. It is avascular, receiving nourishment from vessels in the underlying dermis. Its only innervation (nerve supply) is by unencapsulated (free) nerve endings.
The three layers of the skin are :   # Epidermis, which provides waterproofing and serves as a barrier to infection,  # Dermis, which supports and anchors the skin,  # Hy â¦ podermis (subcutaneous adipose tissue layer).
