Nerve
Saphenous nerve
Largest cutaneous branch of the femoral nerve
High-yield
Purely sensory; the only femoral-nerve branch below the knee. Supplies the medial leg and foot.
Overview
A purely sensory terminal branch of the femoral nerve accompanying the great saphenous vein down the medial leg to the foot.
Reference facts
- Roots
- L3, L4 (from the femoral nerve)
- Course
- Descends through the adductor canal, becomes superficial at the knee, and follows the great saphenous vein along the medial leg
- Motor
- No motor supply - this nerve is purely sensory.
- Sensory
- Medial side of the leg and foot
