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 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 lower layer of the skin is called the dermis. This is the structural layer, the leather of the skin. It holds you together. The dermis is made up mostly of collagen and about 4% elastin fibers. Collagen provides the strength of the skin, while elastin allows it to stretch and snap back.
