Which term refers to a jagged wound or skin tear?

The term "laceration" specifically refers to a jagged wound or skin tear. This type of injury is characterized by irregular edges and often occurs when the skin is torn due to blunt force or sharp objects. Lacerations can vary in depth and severity, which may cause damage to the underlying tissue, making them distinct from other types of wounds.

In contrast, the other terms refer to different kinds of injuries: an incision is a clean cut usually made by a surgical instrument; a contusion is a bruise caused by blunt force trauma that damages blood vessels, leading to swelling and discoloration; an abrasion is a superficial scrape or wearing away of the skin's surface. Each of these terms describes different mechanisms of injury or levels of tissue damage, emphasizing the importance of precise terminology in medical contexts.
