Granulation tissue
Granulation Tissue
Granulation tissue (pronunciation: gran-yuh-ley-shuhn tish-oo) is a type of tissue that forms during the healing process of wounds, ulcers, and inflamed tissues. It is characterized by its pink or red appearance and its granular surface.
Etymology
The term "granulation tissue" is derived from the Latin word "granulum," which means "small grain." This is in reference to the grainy appearance of the tissue.
Definition
Granulation tissue is a new connective tissue and microscopic blood vessels that form on the surfaces of a wound during the healing process. It is often associated with inflammation and is typically seen in healing wounds, ulcers, and inflamed tissues.
Function
The primary function of granulation tissue is to fill in the gap of a wound after an injury. It does this by producing fibroblasts, which are cells that produce collagen and other extracellular matrix proteins. These proteins provide a scaffold for new tissue growth and help to strengthen the wound.
Related Terms
- Fibroblasts: These are cells that produce collagen and other extracellular matrix proteins. They play a crucial role in the formation of granulation tissue.
- Collagen: This is a protein that provides structure to your skin, hair, nails, bones, ligaments, and tendons. It is produced by fibroblasts in the granulation tissue.
- Extracellular Matrix: This is a collection of extracellular molecules secreted by cells that provides structural and biochemical support to the surrounding cells. It is produced by fibroblasts in the granulation tissue.
- Inflammation: This is a biological response to harmful stimuli, such as pathogens, damaged cells, or irritants. It is often associated with the formation of granulation tissue.
