The C2 dermatome corresponds to which region?

• A. Supraclavicular fossa
• B. Upper trapezius
• C. Medial antecubital fossa
• D. Suboccipital

Answer: (D)

Dermatomes map skin areas to a single spinal nerve root. For the cervical nerves, the C2 dermatome runs over the back of the head and the upper neck—the suboccipital region just under the occipital bone. That’s why this area is described as suboccipital. The supraclavicular fossa is linked to C3–C4, the medial antecubital fossa to lower roots around T1, and the upper trapezius area to C3–C4. So the region that matches C2 is the suboccipital area.
