Dissection of anterior aspect of left leg

Deep peroneal nerve; nerve supply to tibialis anterior, extensor digitorum longus and peroneus tertius muscles

The anterior compartment of the leg has been widely opened by retracting the tibialis anterior and extensor digitorum longus muscles (5,11). The course of the deep peroneal nerve (8) through the leg is visible in this view and in the following photographs of the specimen.

1. Anterior tibial recurrent artery
2. Interosseous membrane of leg
3. Lateral surface of tibia (area of origin of tibialis anterior)
4. Muscular branch of deep peroneal nerve (to tibialis anterior muscle)
5. Tibialis anterior muscle (reflected)
6. Periosteal branch of deep peroneal nerve
7. Head of fibula
8. Deep peroneal nerve
9. Muscular branch of deep peroneal nerve
10. Anterior tibial artery (accompanied by anterior tibial veins)
11. Extensor digitorum longus muscle (reflected)
12. Muscular branch of deep peroneal nerve (to extensor digitorum longus muscle and peroneus tertius)
13. Extensor hallucis longus muscle
