Which term means under the skin?

• A. Hypodermal
• B. Subdermal
• C. Subcutaneous
• D. Epidermal

Answer: (C)

The concept tested is terminology for anatomical position relative to the skin. Subcutaneous literally means under the skin, with sub- meaning under and cutaneous relating to the skin. This is the standard term used in medicine to describe tissue beneath the skin, including the fatty layer, and it’s a common site referenced for injections and other procedures. Epidermal refers to the epidermis, the outermost layer of skin, so it’s describing something on or in that top layer rather than beneath the skin. Subdermal would mean under the dermis, which is a more specific depth just below the dermal layer but isn’t the most general or widely used term for “under the skin.” Hypodermal is less common in standard anatomical usage and can be confusing; the widely accepted term for the area beneath the skin is subcutaneous.
