The genitofemoral nerve refers to a human nerve that is found in the abdomen.

The posterior cutaneous nerve of the thigh (also called the posterior femoral cutaneous nerve) provides innervation to the skin of the posterior surface of the thigh and leg, as well as to the skin of the perineum.

The femoral nerve is a nerve in the thigh that supplies skin on the upper thigh and inner leg, and the muscles that extend the knee.

The lumbar plexus is a web of nerves (a nervous plexus) in the lumbar region of the body which forms part of the larger lumbosacral plexus.

The pudendal nerve is the main nerve of the perineum.

The superior gluteal nerve is a nerve that originates in the pelvis and supplies the gluteus medius, the gluteus minimus, and the tensor fasciae latae muscles.

The coccygeal plexus is a plexus of nerves near the coccyx bone.

The nerve to quadratus femoris is a nerve that provides innervation to the quadratus femoris and gemellus inferior muscles.

The lateral plantar nerve (external plantar nerve) is a branch of the tibial nerve, in turn a branch of the sciatic nerve and supplies the skin of the fifth toe and lateral half of the fourth, as well as most of the deep muscles, its distribution being similar to that of the ulnar nerve in the hand.

The posterior scrotal branches (in men) or posterior labial branches (in women) are two in number, medial and lateral.

The posterior branch of the obturator nerve pierces the anterior part of the Obturator externus, and supplies this muscle; it then passes behind the Adductor brevis on the front of the Adductor magnus, where it divides into numerous muscular branches which are distributed to the Adductor magnus and the Adductor brevis [Chung and Chung BRS Gross anatomy 7th edition].

The posterior labial nerves are branches of the pudendal nerve.

The lateral calcaneal branches of sural nerve are cutaneous nerves of the foot providing sensory innervation to the most lateral aspect of skin of the heel.

The proper plantar digital nerves of lateral plantar nerve are nerves of the foot that arise from the superficial branch of the lateral plantar nerve.

The intermediate dorsal cutaneous nerve (external dorsal cutaneous branch), the smaller, passes along the lateral part of the dorsum of the foot, and divides into dorsal digital branches, which supply the contiguous sides of the third and fourth, and of the fourth and fifth toes.

The perforating cutaneous nerve is a cutaneous nerve that supplies skin over the gluteus maximus muscle.

The dorsal nerve of the penis is the deepest division of the pudendal nerve; it accompanies the internal pudendal artery along the ramus of the ischium; it then runs forward along the margin of the inferior ramus of the pubis, between the superior and inferior layers of the fascia of the urogenital diaphragm.

The lateral sural cutaneous nerve (lateral cutaneous branch of the sural nerve) supplies the skin on the posterior and lateral surfaces of the leg.

The perineal branches of the posterior femoral cutaneous nerve are distributed to the skin at the upper and medial side of the thigh.

The perineal nerve is a nerve arising from the pudendal nerve that supplies the perineum.

The medial dorsal cutaneous nerve (internal dorsal cutaneous branch) passes in front of the ankle-joint, and divides into two dorsal digital branches, one of which supplies the medial side of the great toe, the other, the adjacent side of the second and third toes.

The genital branch of the genitofemoral nerve, also known as the external spermatic nerve in males, is a nerve in the abdomen that arises from the genitofemoral nerve.

The Inferior rectal nerves (inferior anal nerves, inferior hemorrhoidal nerve) usually branch from the pudendal nerve but occasionally arises directly from the sacral plexus; they cross the ischiorectal fossa along with the inferior hemorrhoidal vessels, toward the anal canal and the lower end of the rectum, and is distributed to the Sphincter ani externus (external anal sphincter, EAS) and to the integument (skin) around the anus.

The saphenous nerve (long or internal saphenous nerve) is the largest cutaneous branch of the femoral nerve.

The anterior scrotal nerves are branches of the ilioinguinal nerve.

The anterior branch of the obturator nerve is a branch of the obturator nerve found in the pelvis and leg.

The anterior cutaneous branches of the femoral nerve consist of the following nerves: intermediate cutaneous nerve and medial cutaneous nerve.

The anterior labial nerves are branches of the ilioinguinal nerve.

Occasionally the communicating branch to the anterior cutaneous and saphenous branches of the femoral is continued down, as a cutaneous branch, to the thigh and leg, as the cutaneous branch of the obturator nerve.

The proper plantar digital nerves of medial plantar nerve are nerves of the foot.

The medial calcaneal branches of the tibial nerve (internal calcaneal branches) perforate the laciniate ligament, and supply the skin of the heel and medial side of the sole of the foot.

The medial crural cutaneous branches of saphenous nerve provide cutaneous innervation to the medial leg.

The medial sural cutaneous nerve originates from the tibial nerve of the sciatic, descends between the two heads of the Gastrocnemius, and, about the middle of the back of the leg, pierces the deep fascia, and unites with the anastomotic ramus of the common peroneal to form the sural nerve.

The anterior divisions of the lumbar nerves, sacral nerves, and coccygeal nerve form the lumbosacral plexus, the first lumbar nerve being frequently joined by a branch from the twelfth thoracic.

It is a plexus of fine nerves situated in front of the patella, the ligamentum patellae and the upper end of the tibia.

The lateral dorsal cutaneous nerve is a cutaneous branch of the foot.

The deep peroneal nerve (deep fibular nerve) begins at the bifurcation of the common peroneal nerve between the fibula and upper part of the peroneus longus, passes infero-medially, deep to extensor digitorum longus, to the anterior surface of the interosseous membrane, and comes into relation with the anterior tibial artery above the middle of the leg; it then descends with the artery to the front of the ankle-joint, where it divides into a lateral and a medial terminal branch.

The superficial peroneal nerve or superior fibular nerve, innervates the peroneus longus and peroneus brevis muscles and the skin over the antero-lateral aspect of the leg along with the greater part of the dorsum of the foot (with the exception of the first web space, which is innervated by the deep peroneal nerve).

The common plantar digital nerves of lateral plantar nerve are nerves of the foot.

The common plantar digital nerves of medial plantar nerve are nerves of the foot.

The dorsal nerve of the clitoris is a nerve in females that branches off the pudendal nerve to innervate the clitoris.

Dorsal digital nerves of foot are branches of the intermediate dorsal cutaneous nerve, medial dorsal cutaneous nerve, sural nerve and deep fibular nerve.

The lumboinguinal nerve, also known as the femoral or crural branch of genitofemoral, is a nerve in the abdomen.

The deep branch of lateral plantar nerve (muscular branch) accompanies the lateral plantar artery on the deep surface of the tendons of the Flexor muscles and the Adductor hallucis, and supplies all the Interossei (except those in the fourth metatarsal space), the second, third, and fourth Lumbricales.

The deep branch of the perineal nerve (or muscular branches) are distributed to the muscles of the perineum.

The inferior clunial nerves (also called gluteal branches of posterior femoral cutaneous nerve) innervate the skin of the lower part of the buttocks.

The infrapatellar branch of saphenous nerve is a nerve of the lower limb.

The medial plantar nerve (internal plantar nerve), the larger of the two terminal divisions of the tibial nerve (medial and lateral plantar nerve), which accompanies the medial plantar artery.

The sural nerve is a sensory nerve in the calf region (sura) of the leg.
