Tibial nerve

The larger terminal branch of the sciatic nerve. It supplies the muscles of the back of the leg and, through the plantar nerves, the sole.

اہم نکات

• Larger sciatic branch; runs with the posterior tibial artery.
• Supplies the posterior leg + sole.
• Behind the medial malleolus → medial + lateral plantar nerves.
• Passes between the FDL and FHL tendons at the ankle.
• 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.
