The root DERM denotes which tissue type?

• A. Muscle
• B. Nerve
• C. Bone
• D. Skin

Answer: (D)

The root derm- signals skin. It comes from the Greek derma and appears in many terms about the skin, such as dermatology, dermatologist, epidermis (the outer skin layer), and dermis (the middle skin layer). Because derm- is tied to skin, the tissue type described by this root is the skin. Other roots point to different tissues: for example, myo- for muscle, neur- for nerve, and osteo- for bone. So the meaning of derm- is skin, which makes skin the correct answer.
