An animal has a superficial wound. Superficial means:

• A. A wound that is on the extremities of an animal
• B. Near the surface, also called external
• C. On an organ
• D. Deep laceration

Answer: (B)

Superficial means the wound involves only the outermost tissue layers, near the surface, or external. It typically affects the epidermis (and maybe the very superficial dermis) and does not reach deeper structures like muscles, vessels, or internal organs. Because it stays at the surface, such wounds usually bleed minimally and heal primarily by epithelial regeneration with quick recovery if kept clean.

This concept isn’t about where the wound is on the body (extremities) or whether an organ is involved, and it isn’t describing a deep laceration. Those ideas refer to depth and structures involved, which is why they’re not the correct interpretation of superficial.
