avascular
(adjective)
Lacking blood vessels.
Examples of avascular in the following topics:
-
Burns
- This moist, protein-rich avascular environment encourages microbial growth.
- Eschar also restricts distribution of systemically administered antibiotics because of its avascularity.
-
Nerve and Blood Supply
- The articular capsule is highly innervated but avascular (lacking blood and lymph vessels), and receives nutrition from the surrounding blood supply via either the slow process of diffusion or convection, a far more efficient process.
-
Structure, Type, and Location of Cartilage
- Cartilage is an avascular, flexible connective tissue located throughout the body that provides support and cushioning for adjacent tissues.
- Chondrocytes rely on diffusion to obtain nutrients as, unlike bone, cartilage is avascular, meaning there are no vessels to carry blood to cartilage tissue.
-
Serosa
- The epithelial layer, known as mesothelium, consists of a single layer of avascular flat nucleated cells (simple squamous epithelium) which produce the lubricating serous fluid.
-
Characteristics of Epithelial Tissue
- These protein connections hold the cells together to form a tightly connected layer that is avascular but innervated in nature.
-
Serous Membranes
- The epithelial layer, known as mesothelium, consists of a single layer of avascular flat nucleated cells (simple squamous epithelium) which produce the lubricating serous fluid.
-
Cartilage Growth
- However, due to the extremely slow growth of cartilage and its avascular properties, regeneration and growth of cartilage post-injury is still very slow.
-
Synovial Membranes
- Just beneath the intima, most synovium has a dense net of small blood vessels that provide nutrients, not only for synovium, but also for the avascular cartilage.
-
Structure of Synovial Joints
- Just beneath the intima, most synovia have a dense net of small blood vessels that provide nutrients for the synovia and the avascular cartilage.
