The Nerves of The Lower Limb originate from ventral (antrior primary) rami of the lumbar and sacral nerves while creating the lumbar plexus (L1-L4) in the posterior abdominal wall and the sacral plexus (l4-S4) in the pelvis.
The primary nerves of the lower limb are as follows:
- Femoral nerve.
- Obturator nerve.
- Sciatic nerve.
- Tibial nerve.
- Common peroneal nerve.
- Superficial peroneal nerve.
- Deep peroneal nerve.
The last 4 nerves are in fact direct or indirect branches of the sciatic nerve.
The study of these nerves is essential due to their regular engagement in different injuries and peripheral neuropathies.
