Partial-thickness wounds are defined as involving which structures?

• A. Involves deeper tissues such as muscle or bone.
• B. Involves epidermis and part of the dermis.
• C. Involves only epidermis.
• D. Involves subcutaneous tissue and fascia.

Answer: (B)

Partial-thickness wounds extend through the epidermis and into the superficial part of the dermis, but do not reach deeper structures. This depth allows healing mainly by re-epithelialization from the wound edges and from remaining dermal appendages in the superficial dermis. In contrast, injuries that reach deeper tissues like muscle or bone are full-thickness, and injuries involving only the epidermis are superficial or first-degree. So the description that fits partial-thickness is that it involves epidermis and part of the dermis.
