What characterizes a laceration?

A laceration is characterized by a clean or jagged incision through the skin, which may involve various layers of tissue and is often caused by blunt or sharp trauma. This type of wound can vary greatly in size and depth, and the edges of a laceration can be either smooth or uneven, depending on the cause of the injury. Lacerations can also lead to significant bleeding if the underlying blood vessels are damaged.

This option accurately reflects the nature of lacerations, distinguishing them from other types of wounds. For instance, a superficial scrape refers to an abrasion that affects only the outer layer of skin, while a flap of skin that is partially torn away describes a different injury, known as an avulsion. The complete loss of a body part, such as in an amputation, represents a more severe category of injury that is not encompassed by the definition of a laceration.
