Abrasions on elbow and lower arm. The elbow wound will produce a permanent scar. A first-degree abrasion involves only epidermal injury. A second-degree abrasion involves the epidermis as well as the dermis and may bleed slightly. A third-degree abrasion involves damage to the subcutaneous layer and the skin and is often called an avulsion.
Surface roughness resulting from abrasion wear on a spindle. Abrasion is the process of scuffing, scratching, wearing down, marring, or rubbing away. It can be intentionally imposed in a controlled process using an abrasive. Abrasion can be an undesirable effect of exposure to normal use or exposure to the elements.
Corneal abrasion is a scratch to the surface of the cornea of the eye. [3] Symptoms include pain, redness, light sensitivity, and a feeling like a foreign body is in the eye. [1] Most people recover completely within three days. [1] Most cases are due to minor trauma to the eye such as that which can occur with contact lens use or from ...
A wound is any disruption of or damage to living tissue, such as skin, mucous membranes, or organs. [1] [2] 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.

Friction burn caused by a treadmill. Example of a third-degree friction burn. A friction burn is a form of abrasion caused by the friction of skin rubbing against a surface. A friction burn may also be referred to as skinning, chafing, or a term named for the surface causing the burn such as rope burn, carpet burn or rug burn.
Corneal abrasions are a common injury caused by contact with foreign objects. The eye can also be injured by a foreign object remaining in the cornea. Radiation damage can be caused by exposure to excessive light, often caused by welding without eye protection or being exposed to excessive ultraviolet radiation, such as sunlight.
Causes of wear can be mechanical (e.g., erosion) or chemical (e.g., corrosion). The study of wear and related processes is referred to as tribology . Wear in machine elements , together with other processes such as fatigue and creep , causes functional surfaces to degrade, eventually leading to material failure or loss of functionality.
Abrasion (dental), the loss of tooth structure by mechanical forces from a foreign element; Abrasion (medical), a wound consisting of superficial damage to the skin; Abrasion (mechanical), the process of scuffing, scratching, wearing down, marring, or rubbing away; Abrasion (geology), mechanical scraping of a surface by friction between moving ...
