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 sun's rays can break down these proteins and, eventually, the skin begins to wrinkle and sag. The subcutaneous layer, or subcutis, is a layer of fatty tissue that provides nourishment to the dermis and upper layers of skin. It also conserves body heat and cushions internal organs against trauma.Blood vessels, nerves, sweat glands and deeper hair follicles extend from the dermis into the fat (hypodermis).he sun's rays can break down these proteins and, eventually, the skin begins to wrinkle and sag.
