Extensor hallucis brevis is located in which region of the foot?

• A. Plantar surface
• B. Medial arch
• C. Lateral malleolar region
• D. Dorsum

Answer: (D)

Extensor hallucis brevis sits on the top surface of the foot. It’s a short extensor muscle that originates from the dorsal aspect of the calcaneus and inserts into the proximal phalanx of the big toe, enabling extension at the metatarsophalangeal joint. This dorsal location distinguishes it from muscles on the plantar surface (sole) or near the ankle. So, the region is the dorsum of the foot.
