What is a laceration?

A laceration is best defined as a wound where the flesh has incurred an irregular tear. This type of injury typically results from blunt force trauma, leading to jagged or irregular edges in the skin that can vary in depth and severity. Lacerations often occur in accidents involving falls, collisions, or other forms of impact where skin is stretched and torn rather than cut cleanly, which distinguishes them from incisions.

In contrast, other types of injuries mentioned in the choices—such as cuts resulting from sharp objects, burns affecting all skin layers, or allergic reactions causing skin irritation—are characterized by different mechanisms and healing processes. Understanding the nature of lacerations is critical for appropriate treatment, which may involve cleaning the wound, controlling bleeding, and, in some cases, suturing to promote proper healing and minimize scarring.
