Obturator nerve-branch to anterior, medial and posterior proximal thigh
Posterior femoral cutaneous nerve-to posterior thigh and popliteal region
Sciatic nerve
Supplies foot and most of leg
Via sural, common, superficial, and deep fibular nerves
Cluneal nerves (superior middle and inferior)-buttock
Nerves to muscles of lower limb from lumbosacral plexus
Nerves in the gluteal region

Emerges superior to piriformis
Supplies gluteus medius, gluteus minimus and tensor fasciae latae
Inferior gluteal nerve (L5-S2)
Inferior to piriformis
Supplies gluteus maximus
Nerve to quadratus femoris (L4-S1): also supplies inferior gemellus
Pudendal nerve (S2-S4): supplies the perineum (not structures in the gluteal region)
Nerve to obturator internus (L5-S2)
Nerves to anterior and lateral thigh
Femoral nerve (L2-L4)
Enters thigh lateral and deep to femoral artery
Supplies the anterior compartment of the thigh
