Which type of wound results from pressure applied by a ligature?

A wound resulting from pressure applied by a ligature is classified as an abrasion. An abrasion occurs when the skin's surface is scraped or worn away, typically involving the removal of the epidermis. When a ligature is tightened around a body part, it can lead to friction and pressure that results in the upper layers of skin being damaged or scraped off.

Contusions, on the other hand, are bruises that result from blunt force trauma causing blood vessels to rupture beneath the skin without breaking the skin's surface. Lacerations are cuts produced by sharp objects, leading to irregular, torn edges, while incisions are clean, straight cuts usually made by a sharp instrument. Therefore, none of these other types of wounds accurately describe the result of pressure from a ligature like an abrasion does.
