Anatomy of Lumbar Plexus
Lumbar Plexus Formed by ventral rami of L1, L2, L3 and part of L4.
These rami of the Lumbar Plexus divide into Two Division
- 1. Dorsal Division
- 2. Ventral Divisions.
From the ventral divisions of the Lumbar Plexus give rise to
- ilioinguinal (L1),
- genitofemoral (L1, L2),
- obturator(L2,L3, L4),
- accessory obturator (L3,L4) nerves.
The dorsal divisions of these rami of Lumbar Plexus give rise to
- lateral cutaneous nerve of thigh (L2, L3)
- femoral nerve (L2,L3,L4)
Iliohypogastric contains fibres of both ventral and dorsal divisions (L1)
