Iliohypogastric and ilioinguinal nerves
The two branches of the first lumbar nerve that supply the lowest part of the anterior abdominal wall, running like the lower intercostal nerves but without entering the rectus sheath.
اہم نکات
- Both from L1 (lumbar plexus).
- Iliohypogastric pierces the external oblique above the superficial ring.
- Ilioinguinal passes through the superficial ring.
- Skin above the pubis = L1.
- Ventral root: basal-lamina neurons. Dorsal root: neural-crest ganglion cells.
- Schwann cells: neural crest.
- Nerve: epineurium → perineurium (blood–nerve barrier) → endoneurium.
- Cut nerve: Wallerian degeneration; regrows 0.5–3 mm/day.
