1

what is the mnumonic for the lumbar plexus?

Even Eddie Favors Bow Tie Line V-Links Says It Is Great Lunch For Outdoors.

2

How do we draw the Lumbar Plexus?

Draw an 'E' and then another 'E" and then a 'F' and then a bow tie and then a line and connects it with  "v-link" and then labal with S.I.I.G.L.F.O for the nerves:

Subcostal; Iioinguinal, iliohypogastric, genital femoral, lateral femoral cutaneous, femoral, and obtorator.

Don't forget to label the nerve levels:  T12, L1, L2, L3, L4.

3

What skin does the Lateral femoral cutaneous innervate?

the Anterior lateral thigh

A image thumb
4

what skin does the femoral nerve innervate?

It will innervate the anterior middle thigh, and the medial lower leg thorugh the Anterior femoral cutaneous and the Safinous nerves.

5

What does sensory of the skin innervation to the front of the lower limb?

the sciatic nerve that becomes the common fibular cutaneous nerve, that becomes the superfical fibular nerve and the deep fibular nerve

and finally at the lateral spot of the foot is the sural nerve.

6

What innervates the muscles of the thigh?

the Anterior compartment of the thigh is innervated by the femoral nerve, the medial thigh is innervated by the obterator nerve. and the posterior thigh is innervated by the tibial nerve.

what is the primary action of the different compartments of the thigh?

the anterior: Extension

Posterior: Flexion
