12/1 Anatomy of Lower Limb!

Question 1

what is the mnumonic for the lumbar plexus?

Answer 1

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

Answer 2

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.
