There are three major nerves in the thigh- femoral, obturatory and sciatic. In the leg, the three major nerves are the tibial, superficial peroneal and deep peroneal. The foot has the medial plantar, lateral plantar and deep peroneal. There is a superior and inferior gluteal nerve.
Femoral innervates pectineus, sartorius, quadriceps femoris. Obturator innervates: anterior- pectineus, adductor brevis, adductor longus, gracilis. Posterior- obturator externus, adductor magnus.
Sciatic nerve innervates, in the thigh: tibial- adductor
magnus, hamstrings; common peroneal- biceps. In the leg: tibial nerve to posterior compartment, superficial peroneal to lateral compartment, deep peroneal to anterior compartment. In the foor: deep peroneal- extensor digitorum and hallucis brevis; lateral plantar peroneal- quadriceps plantae, hypothenar lumbricals 2-4, interossei. Medial plantar- flexor digitorum brevis, thenars, first lumbrical.
Dermatome map varies from person to person.
Adductor canal contains many of the thigh arteries. There are three major arteries of the hip, leg, thigh and foot. Perforating arteries of the deep femoral supply the thigh and move along with the movement of the thigh muscles. Venous system is on the whole more superficial.
