An example of complete regeneration without an interruption of the morphology is non-injured tissue, such as skin. [73] Non-injured skin has a continued replacement and regeneration of cells which always results in complete regeneration. [73] There is a subtle distinction between 'repair' and 'regeneration'.
Lacerations – irregular tear-like wounds caused by some blunt trauma. Lacerations and incisions may appear linear (regular) or stellate (irregular). The term laceration is commonly misused in reference to incisions. [9] Abrasions (grazes) – superficial wounds in which the topmost layer of the skin (the epidermis) is
A strain is a type of acute injury that occurs to the muscle or tendon. Similar to sprains, it can vary in severity, from a stretching of the muscle or tendon to a complete tear of the tendon from the muscle. Some of the most common places that strains occur are in the foot, back of the leg (hamstring), or back. [2]
In medicine, an avulsion is an injury in which a body structure is torn off by either trauma or surgery (from the Latin avellere, meaning "to tear off"). [1] The term most commonly refers to a surface trauma where all layers of the skin have been torn away, exposing the underlying structures (i.e., subcutaneous tissue, muscle, tendons, or bone).
An abrasion is a partial thickness wound caused by damage to the skin. [1] It can be superficial, which involves only the epidermis, or deep, which involves the deep dermis. Abrasions usually involve minimal bleeding.
Microtrauma to the skin (compression, impact, abrasion) can also cause increases in a skin's thickness, as seen from the calluses formed from running barefoot or the hand calluses that result from rock climbing. This might be due to increased skin cell replication at sites under stress where cells rapidly slough off or undergo compression or ...
Skin trauma is serious and altering physical injury experienced by the skin or multiple layers of epithelial tissues. [1] This can be in the form of cuts, burns ...
The skin is susceptible to burns, and burns to the skin often cause blistering. Abrasive trauma scrapes or rubs off the skin, and severe abrasions require skin grafting to repair. Skin tears involve the removal of the epidermis or dermis through friction or shearing forces, often in vulnerable populations such as the elderly.
