How is an abrasion typically defined?

An abrasion is typically defined as a scrape or rub on the skin. This type of injury occurs when the outer layer of skin, known as the epidermis, is worn away due to friction against a rough surface. Abrasions can happen from various activities, such as falling or scraping against objects, and they usually result in superficial damage without deeper tissue involvement.

This definition encapsulates the core of what an abrasion is and highlights its characteristics, including its common causes and the fact that it tends to be less severe than other types of wounds like punctures or cuts. Abrasions may or may not bleed and can be at risk for infection, depending on the circumstances surrounding the injury.
