Injuries

A wound is any disruption of or damage to living tissue, such as skin, mucous membranes, or organs. Wounds can either be the sudden result of direct trauma (mechanical, thermal, chemical), or can develop slowly over time due to underlying disease processes such as diabetes mellitus, venous/arterial insufficiency, or immunologic disease. Wounds can vary greatly in their appearance depending on wound location, injury mechanism, depth of injury, timing of onset (acute vs chronic), and wound sterility, among other factors. Treatment strategies for wounds will vary based on the classification of th

A bruise, also known as a contusion, is a type of hematoma of tissue, the most common cause being capillaries damaged by trauma, causing localized bleeding that extravasates into the surrounding interstitial tissues. Most bruises occur close enough to the epidermis such that the bleeding causes a visible discoloration. The bruise then remains visible until the blood is either absorbed by tissues or cleared by immune system action. Bruises which do not blanch under pressure can involve capillaries at the level of skin, subcutaneous tissue, muscle, or bone.

A hickey, also known as love bite, is a bruise or bruise-like mark caused by sucking or biting the skin of a person, usually their neck. While biting may be part of giving a hickey, sucking is sufficient to burst small superficial blood vessels under the skin to produce bruising. A hickey is sometimes used to mark someone as being the target of a partner's romantic affection or as belonging to them.

Medicine includes the process by which the cells in the body regenerate and repair to reduce the size of a damaged or necrotic area and replace it with new living tissue. The replacement can happen in two ways: by regeneration in which the necrotic cells are replaced by new cells that form "like" tissue as was originally there; or by repair in

A splinter (also known as a sliver) is a fragment of a larger object, or a foreign body that becomes embedded in a body. To be considered a splinter, the foreign body must penetrate and remain lodged within the tissue. Splinters may cause initial pain due to the damage of flesh and muscle, and can cause an infection through contamination by bacteria on the foreign object.

The word is derived from "electro" and "execution", but it is also used for accidental death.

Finger degloving and amputation|300px|thumb Degloving occurs when skin and the fat below it, the subcutaneous tissue, are torn away from the underlying anatomical structures they are normally attached to. It is a type of avulsion. Normally the subcutaneous tissue layer is attached to the fibrous layer that covers muscles known as deep fascia.
