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 overall dermis is vascular. The only part that could be avascular are the dermal papillae (upper part of the dermis), but this would be the exception rather than the rule because most dermal papillae contain blood vessels.Just to point out, you asked which part of the DERMIS does not contain any blood vessels.The epidermis is avascular as the answers above have mentioned, but the epidermis is not part of the dermis. The dermis and epidermis are two separate and distinct parts of the skin.ust to point out, you asked which part of the DERMIS does not contain any blood vessels.
