The epidermis has no blood vessels.
Lichen planus is a self allergy of the skin or mouth which affects mostly middle age people. Avascular necrosis is the dead bone tissue caused by lack of blood supply which is also found usually in middle age people
Yes, stratified squamous epithelium is avascular, meaning it does not contain blood vessels. Nutrients and oxygen are supplied to the cells through diffusion from underlying tissues.
No, the cornea is a transparent, avascular tissue that lacks blood vessels and nerves. It is composed of specialized cells called keratocytes that help maintain its structure and transparency.
Avascular tissues have limited access to blood supply, which is important for delivering oxygen and nutrients necessary for healing. Without sufficient blood flow, the healing process is slowed down in avascular tissues.
The cornea is the part of the eye that is avascular, meaning it does not have blood vessels. Instead, it receives nutrients and oxygen directly from tears on its surface and the surrounding aqueous humor.

Epidermis
The term "avascular" actually means lacking in blood vessels. What we call "skin" is actually layers of epithelial tissue, all of which is avascular. So, I suppose all parts of the skin are avascular, but epithelial tissue doe lie upon a layer of vascular connective tissue.
The epidermis of the skin has no blood supply.
The stratum corneum is the outermost layer of the epidermis and is avascular, meaning it lacks blood vessels. This layer is made up of dead skin cells that provide a protective barrier for the underlying layers of skin.
Yes, the epidermis itself is avascular, because the cells of the epidermis are not alive. The dermis layer of skin however, relies on blood vessels.
The cornea is the avascular structure of the eye that allows light to enter. It is a transparent outer covering that refracts light onto the lens.
"Avascular but innervated" means that a tissue or structure lacks a direct blood supply (avascular), but it still has nerve supply (innervated). This usually indicates that the tissue relies on diffusion for its nutrient and oxygen supply, while still being able to communicate with the nervous system. Examples include the cornea of the eye and cartilage in joints.
No. Avascular means that it does not get blood.
Yes, a Venus Flytrap is avascular.
Tissue without capillaries is called avascular tissue. Examples of avascular tissue include:CartilageEpitheliaCorneaLensAll organs contain blood vessels.
All epithelial tissue is avascular
