INNERVATION

Question 1

how many nerves supply the ankle joint and how do they pass? where do they arise?

Answer 1

4 nerves that pass superficially and arise at the level of the alveoli

Question 2

• sends branches to the ankle joint as it passes along the posteromedial aspect; it is deep to the fascia cruris

Answer 2

Tibial Nerve

Question 3

• sends branches to the ankle joint as it passes along the anterior aspect; it is deep to the fascia cruris at this level

Answer 3

Deep Fibular Nerve / Deep Peroneal Nerve

Question 4

• sends branches to the ankle joint as it passes over the posterior lateral aspect; it is in the superficial fascia

Answer 4

Sural Nerve

Question 5

• sends branches to the ankle joint as it passes over the anterior medial aspect; it is in the superficial fascia

Answer 5

Saphenous Nerve

Question 6

• crosses the ankle joint at the anterior lateral aspect, but normally does not provide innervation to the ankle joint (probably because it would be easily injured from an inversion ankle sprain)

Answer 6

Superficial Fibular Nerve / Superficial Peroneal Nerve
