Cuts and puncture wounds

Wound - cut or puncture; Open wound; Laceration; Puncture wound

A cut is a break or opening in the skin. It is also called a laceration. A cut may be deep, smooth, or jagged. It may be near the surface of the skin, or deeper. A deep cut can affect tendons, muscles, ligaments, nerves, blood vessels, or bone.

A puncture is a wound made by a pointed object such as a nail, knife, or sharp tooth. Puncture wounds often appear to be on the surface, but may extend into the deeper tissue layers.
