Fibromuscular tissue, in the context of vascular disorders, refers to tissue where the normal cells of an artery wall have been replaced by fibrous cells. These fibrous cells are less flexible and strong than the original cells.
Understanding Fibromuscular Tissue in Fibromuscular Dysplasia (FMD)
Fibromuscular dysplasia (FMD) provides a key example. In FMD, some of the strong, flexible cells in an artery are replaced by fibromuscular tissue, which is composed of less flexible and strong fibrous cells.
- Impact on Arteries: This cellular change causes the arteries to become stiffer and more susceptible to damage.
Characteristics of Fibromuscular Tissue
| Feature | Description |
|---|---|
| Composition | Primarily consists of fibrous cells, replacing normal arterial cells. |
| Strength | Weaker compared to the original cells of the artery wall. |
| Flexibility | Less flexible than the original cells of the artery wall. |
| Location (in FMD) | Found within the walls of arteries affected by fibromuscular dysplasia. |
