A scar (or scar tissue) is an area of fibrous tissue that replaces normal skin after an injury. Scars result from the biological process of wound repair in the skin, as well as in other organs , and tissues of the body.
Adhesions form as a natural part of the body's healing process after surgery in a similar way that a scar forms. The term "adhesion" is applied when the scar extends from within one tissue across to another, usually across a virtual space such as the peritoneal cavity. Adhesion formation post-surgery typically occurs when two injured surfaces ...
Keloid, also known as keloid disorder and keloidal scar, [1] is the formation of a type of scar which, ... Keloids form within scar tissue. Collagen, ...
Timing is important to wound healing. Critically, the timing of wound re-epithelialization can decide the outcome of the healing. [11] If the epithelization of tissue over a denuded area is slow, a scar will form over many weeks, or months; [12] [13] If the epithelization of a wounded area is fast, the healing will result in regeneration.
Brain healing is the process that occurs after the brain has been damaged. If an individual survives brain damage, the brain has a remarkable ability to adapt. When cells in the brain are damaged and die, for instance by stroke, there will be no repair or scar formation for those cells.
Granulation tissue is composed of tissue matrix supporting a variety of cell types, [3] most of which can be associated with one of the following functions: formation of extracellular matrix; operation of the immune system; vascularisation; An excess of granulation tissue (caro luxurians) is informally referred to as "proud flesh".

Fibrosis occurs within the same organ, the fibrotic scar tissue within skeletal muscle known as myofibrosis, limits muscle contractibility and stiffens muscles. [13] [14] [15] Muscle injury (such as a large burn or surgery) can cause muscle contractures as internal scar tissue (adhesions and fibrosis) develops.
Cicatrization, also spelled cicatrisation (from Latin cicatrix, meaning "scar"), is the contraction of fibrous tissue formed at a wound site by fibroblasts, reducing the size of the wound while distorting tissue. It may refer to: The process of a wound healing to produce scar tissue
