Anatomy of the Deep Peroneal Nerve

Which muscle does not receive muscular branches from the medial plantar nerve?

Which nerve supplies the skin of the cleft between the 1st and 2nd toes?

Which of the following muscles does not receive muscular branches from the lateral plantar nerve?

Which articular branch supplies the ankle joint?

Which nerve is the continuation of the tibial (medial popliteal) nerve at the lower border of the popliteus muscle?

Which nerve divides deep to flexor retinaculum into a medial and lateral plantar nerve?

Deep Peroneal Nerve

Divides into 2 terminal branches
Cutaneous branches supply skin of the cleft between the 1st and 2nd toes
Muscular branches supply all 4 muscles of the anterior compartment of the leg
Articular branches supply the ankle joint

Tibial Nerve

Continuation of the tibial (medial) popliteal nerve
Descends between superficial and deep flexors of the back of the leg
Divides deep to the flexor retinaculum into a medial and lateral plantar nerve

Medial Plantar Nerve

Larger of the two terminal branches of the tibial nerve
Muscular branches supply:
- Abductor hallucis
- Flexor digitorum brevis
Cutaneous branches supply:
- Skin of the medial 2/3 of the sole
- Skin of the plantar surface of the medial 3 ½ toes

Lateral Plantar Nerve

Smaller of the two terminal branches of the tibial nerve
Muscular branches supply:
- Abductor digit minimi
- Flexor digitorum accessorius
- All 7 interosseus muscles
Cutaneous branches supply:
- Skin of the lateral part of the sole
- Skin of the plantar surface of the lateral 1 ½ toes

This quiz covers the anatomy of the deep peroneal nerve, including its branches and the areas it supplies. It also covers the relations and divisions of the nerve.
