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

The type of wound that results from pressure applied by a ligature is an abrasion. An abrasion occurs when the skin is scraped or rubbed off due to contact with a rough surface, which can include situations where a ligature applies pressure against the skin. In this case, a ligature can cause the topmost layers of skin to be damaged without breaking through to deeper tissues. It typically presents as a superficial wound with a raw or scraped appearance.

Contusions, on the other hand, are bruises caused by blunt force trauma that leads to bleeding underneath the skin without breaking it. Lacerations are tears or cuts in the skin due to sharp objects, while incisions are a type of cut made by a sharp instrument, usually with clean edges. Each of these other types of wounds has different mechanisms and characteristics that do not specifically relate to the pressure applied by a ligature. Therefore, the best answer in this context is an abrasion, as it directly describes the effect of pressure on the skin by the ligature.
