plantar nerve plantar nerve the plantar nerves are a pair of nerves innervating the sole of the foot. they arise from the posterior branch of the tibial nerve. diagram of the segmental distribution of the cutaneous nerves of the sole of the foot medial plantar nerve main article: medial plantar nerve the medial plantar nerve supplies: the abductor hallucis, the flexor digitorum brevis, the flexor hallucis brevis and the first lumbrical. cutaneous distribution of the medial plantar nerve is to the medial sole and medial three and one half toes, including the nail beds on the dorsum (like the median nerve in the hand). mnemonic laff muscles (pronounced "laugh") l – first lumbrical, a – abductor hallucis, f – flexor digitorum brevis, f – flexor hallucis brevis lateral plantar nerve main article: lateral plantar nerve the lateral plantar nerve supplies quadratus plantae, flexor digiti minimi brevis, adductor hallucis, the dorsal and plantar interossei, three lateral lumbricals and abductor digiti minimi. cutaneous innervation is to the lateral sole and lateral one and one half toes (like the ulnar nerve). nerves of the lumbosacral plexuslumbar plexusiliohypogastric lateral cutaneous branch anterior cutaneous branch ilioinguinal anterior scrotal ♂/labial ♀ genitofemoral femoral branch genital branch lateral cutaneous patellar obturator anterior cutaneous posterior accessory femoral anterior cutaneous branches saphenous infrapatellar medial crural cutaneous sacral plexussciaticcommon fibular lateral sural cutaneous communicating branch deep fibular lateral terminal branch medial terminal branch dorsal digital superficial fibular medial dorsal cutaneous intermediate dorsal cutaneous dorsal digital tibial medial sural cutaneous medial calcaneal medial plantar (common plantar digital nerves proper plantar digital) lateral plantar (deep branch superficial branch common plantar digital proper plantar digital) sural lateral dorsal cutaneous lateral calcaneal other muscular superior gluteal inferior gluteal lateral rotator group (to quadratus femoris to obturator internus to the piriformis)cutaneous: posterior cutaneous of thigh (inferior cluneal perineal branches) perforating cutaneous coccygeal plexus pudendal inferior anal perineal deep posterior scrotal♂ / labial♀ dorsal of the penis♂ / clitoris♀ anococcygeal related nerve supply of the human leg
