Which type of wound has jagged edges?

• A. Puncture
• B. Laceration
• C. Abrasion
• D. Incision

Answer: (B)

Jagged, irregular borders come from tearing tissue, which is the hallmark of a laceration. When skin is torn by blunt force or stretching, the edges pull apart unevenly, and underlying tissue can be damaged. A clean, straight edge is more typical of an incision, made by a sharp object. An abrasion is a superficial scrape with loss of the outer skin, resulting in a rough, scraped surface rather than torn edges. A puncture wound is a small entry hole caused by a pointed object and often goes deeper with a narrow opening, not jagged tearing. Therefore, the wound with jagged edges is a laceration.
