a. Femoral, Obturator, and Sciatic
b. Radial, Ulnar, and Median
c. Tibial, Fibular, and Saphenous
d. Axillary, Musculocutaneous, and Radial

Answer 1

The three major nerves of the Lumbosacral Plexus are Tibial nerve, Fibular nerve, and Saphenous nerve.

Step-by-step explanation:

The three major nerves of the Lumbosacral Plexus are:

1. Tibial nerve: It is a systemic nerve from the sacral plexus that extends across the hip joint and gluteal region into the upper posterior leg.
2. Fibular nerve: Another systemic nerve from the sacral plexus that accompanies the tibial nerve and branches into the lower leg and foot.
3. Saphenous nerve: It is a branch from the femoral nerve which is one of the major nerves of the lumbar plexus. The saphenous nerve extends through the anterior lower leg.
