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.
Persons with thin skin have a thin epidermis. The subcutaneous layer, the third layer of skin, is located beneath the dermis and consists of areolar (minute spaces in tissue) and adipose (fat) tissues. The first skin layer is fixed to the second skin layer as though the two were glued together. The second and third skin layers are attached in a different way. Fibers from the second layer (the dermis) extend down into the third layer (subcutaneous), anchoring the two layers together.
