Subcutaneous tissue lies between which structures?

Subcutaneous tissue lies between which structures?

• A. In the dermal layer
• B. Between the skin and the muscle
• C. In the bone marrow
• D. In the vein

Answer: (B)

Subcutaneous tissue, or the hypodermis, sits beneath the dermis of the skin and above the underlying muscle. It’s the fatty, cushioned layer that provides insulation and padding. So it lies between the skin and the muscle, not in the dermal layer, not in bone marrow, and not within a vein. This placement is why subcutaneous injections are given into that layer just under the skin.
