Extensor hallucis longus
Lower legs
Deep muscle — it lies under other muscles. X-ray makes the muscles over it see-through.
- Origin
- Middle of the front of the fibula and the interosseous membrane
- Insertion
- Base of the distal phalanx of the big toe
- Action
- Extends the big toe; assists dorsiflexion
- Nerve supply

A thin muscle on the front of the lower leg, between the tibialis anterior and the extensor digitorum longus. Its tendon is easy to see on top of the foot when you lift the big toe.
