Cutaneous Territories of Peripheral Nerves Flashcards
Outline the cutaneous distributions of the femoral nerve.
Anterior cutaneous branches – derived from the anterior division of the femoral nerve. They supply the skin of the anteromedial thigh.
Saphenous nerve – a continuation of the posterior division of the femoral nerve. It supplies the skin of the medial leg and foot.
Outline the cutaneous distributions of the obturator nerve.
Medial thigh.
Outline the cutaneous distributions of the sciatic nerve.
The sciatic nerve does not have any direct cutaneous functions. It does provide indirect sensory innervation via its terminal branches:
- Tibial nerve – supplies the skin of the sole of the foot (forefoot and calcaneal).
- Common fibular nerve – supplies the skin of the lateral leg and the dorsum of the foot.
These two give off a branch, forming the sural nerve.
Outline the cutaneous territories of the tibial nerve.
Sole of the forefoot and heel.
Outline the different branches of the common fibular nerve, and the only area that it purely supplies.
The common fibular nerve gives off branches to:
- Sural; lateral cutaneous and communicating.
- Deep fibular.
- Superficial fibular.
Supplies the proximal lateral leg.
Outline the cutaneous distributions of the superficial fibular nerve.
Distal anterolateral leg and dorsum of the foot (excluding the first webbed space).
Outline the cutaneous distributions of the deep peroneal nerve.
Supplies the first webbed space on the dorsum of the foot.
Outline the cutaneous distribution for the lateral cutaneous nerve of the thigh.
The anterolateral aspect of the thigh.
Outline the cutaneous distribution of the sural nerve.
The posterolateral aspect of the leg and lateral aspect of the foot.
Outline the cutaneous distributions of the saphenous nerve.
The medial aspect of the leg and medial border of the foot.
Label the cutaneous distributions of the leg.
Outline the cutaneous distributions for the sole of the foot.
Outline the cutaneous distributions for the lower limb.
