Which anatomical layer lies immediately under the skin and can be involved in subcutaneous infections?

• A. Dermis
• B. Epidermis
• C. Subcutaneous Tissue
• D. Fascia

Answer: (C)

The layer just beneath the skin is the subcutaneous tissue (hypodermis). It lies under the dermis and consists mainly of fat and loose connective tissue, along with small vessels and nerves. This loose, fatty layer is a common site for subcutaneous infections because bacteria can spread easily through the fat and connective tissue, leading to localized inflammation, swelling, warmth, and sometimes abscess formation. The epidermis is the outermost protective layer, the dermis sits just beneath it as part of the skin itself, and fascia lies deeper around muscles; infections in the latter are not described as subcutaneous infections.
