Saphenous nerve

The longest cutaneous branch of the femoral nerve, supplying the medial side of the leg and foot.

Key points

• Femoral nerve (posterior division).
• Adductor canal → medial knee → with the great saphenous vein.
• Skin of the medial leg and foot.
• Upper limb nerves: C4–T2 segments; lower limb: L2–S2.
• Ventral root: basal-lamina neurons. Dorsal root: neural-crest ganglion cells.
• Nerve: epineurium → perineurium (blood–nerve barrier) → endoneurium.
• Cut nerve: Wallerian degeneration; regrows 0.5–3 mm/day.
