What is Internal Scar Tissue?

Scar tissue refers to the fibrous connective tissue in the aging stage of granulation tissue after reconstruction and maturation. In the case of trauma, fibroblasts divide, proliferate, migrate to the damaged site, generate extracellular matrix, form scar tissue, and repair the wound.

Scar tissue

Right!

Scar tissue refers to

Gross eye : Partially contracted, pale or gray, translucent, firm and tough, lacking elasticity.

Under the microscope : a large number of parallel or staggered

Fill the wound defect and maintain the integrity of tissues and organs;

Scar contraction, scar contraction is different from the early contraction of the wound, but the scar becomes smaller in volume due to the significant reduction of water in the later period, and the contraction of the myofibroblast causes the contraction of the entire scar. Due to the toughness and lack of elasticity of the scar, and the shrinkage of the scar can cause organ deformation and dysfunction, scars that occur near the joints and important organs often cause joint spasms or restricted movement, such as in the digestive tract, urinary tract and other chambers Organs cause narrowing of the lumen and movement disorders near the joints.

Scar adhesions, scar adhesions that occur between organs or between the organ and the body cavity wall, often affect their function to varying degrees. If extensive fibrosis and vitreous changes occur after extensive damage in the organ, the organ will harden.

Hypertrophy of scar tissue is also called "hypertrophic scar". If this hypertrophic scar protrudes from the surface of the skin and spreads irregularly beyond the original damage area, it is called "keloid", also known as "crab foot swollen." Wounds that are susceptible to burns or repeated irritation by foreign bodies are generally considered to be related to skin tension and physical fitness. Those who are prone to keloids are called scars . Its molecular mechanism is unknown. Some mast cells are common around the blood vessels in keloids. Therefore, it is believed that due to continuous local inflammation and hypoxia, mast cells promote the secretion of multiple growth factors and cause the granulation tissue to grow excessively, thus forming keloids.
