Nerve Pathway

Question 1

Femoral Nerve Pathway (L,2,3,4)

Answer 1

Lateral of Psoas major
passes deep to inguinal ligament
enters femoral triangle
it divides to anterior thigh

Question 2

Obturator Nerve (L2,3,4)

Answer 2

Medial aspect of psoas major
Obturator foramen
Medial compartment of the thigh

Question 3

Sciatic Nerve (L4-S3)

Answer 3

exits pelvis via greater sciatic foramen inferior to piriformis
Divides into the common fibular and tibial branches at the superior angle of the popliteal fossa

Question 4

Tibial Nerve (l4-s3)

Answer 4

Medial branch of sciatic nerve at the superior angle of popliteal fossa

Passes under tendinous arch of soleus to enter deep posterior compartment of the leg

Passes posterior to medial malleolus

Passes under flexor retinacilim b/w flex dig/hall long

Divides into medial and lateral plantar nerves

Question 5

Common Fibular Nerve (L4-S2)

Answer 5

Lateral branch of sciatic nerve at the popliteal fossa

Winds around neck of fibula

Passes deep to fibularis longus

Divides into superficial & deep fibular nerves

Question 6

Deep Fibular Nerve L4-S2

Answer 6

B/w neck of fibula & fibularis longus

Passes under extensor retinaculum b/w ext. Hall Long and Ext Dig Longus

Runs over the dorsum of foor lateral to Ext Hall Longus
