Avulsion An injury in which soft tissue either is torn completely loose or is hanging as a flap.
Burn An injury in which the soft tissue receives more energy than it can absorb without injury from thermal heat, frictional heat, toxic chemicals, electricity, or nuclear radiation.
Closed injury Injury in which damage occurs beneath the skin or mucous membrane but the surface remains intact
Compartment syndrome Swelling in a confined space that produced dangerous pressure; may cut off blood flow or damage sensitive tissue.
Contamination The presence of infective organisms or foreign bodies such as dirt, gravel, or metal.
Contusion A bruise without a break in the skin
Dermis The inner layer of the skin, containing hair follicles, sweat glands, nerve endings, and blood vessels.
Ecchymosis discoloration associated with a closed wound; signifies bleeding.
Epidermis The outer layer of skin that acts as a watertight protective covering
Evisceration The displacement of organs outside the body
Full-thickness burn A burn that affects all skin layers and may affect the subcutaneous layers, muscle, bone, and internal organs, leaving the area dry, leathery, and white, dark brown or charred; traditionally called a third-degree burn.

Occlusive dressing Dressing made of vaseline gauze, aluminum foil, or plastic that prevents air and liquids from entering or exiting a wound.
Open injury An injury in which there is a break in the surface of the skin or the mucous membrane, exposing deeper tissue to potential contamination
Partial-thickness burn A burn affecting th epidermis and some portion of the dermis but not the subcutaneous tissue, characterized by blisters and skin that is white to red, moist, and mottled; traditionally called a second-degree burn.
Penetrating wound An injury resulting from a sharp, pointed object.
