Nerve: Genital branch of genitofemoral nerve
Deep and superficial dissection of the lumbar plexus. (External spermatic branch of genitofemoral labeled at bottom right.)
Latin ramus genitalis nervi genitofemoralis
Gray's subject #212 953
Innervates cremaster
Dorlands/Elsevier r_02/12690192

The genital branch of the genitofemoral nerve (external spermatic nerve) passes outward on the Psoas major, and pierces the fascia transversalis, or passes through the abdominal inguinal ring; it then descends behind the spermatic cord to the scrotum, supplies the Cremaster, and gives a few filaments to the skin of the scrotum. Grays Fig. ... Latin is an ancient Indo-European language originally spoken in Latium, the region immediately surrounding Rome. ... The word cremaster can mean more than one thing: In humans, the cremaster muscle is a muscle that is part of genital anatomy. ... Elseviers logo Elsevier, the worlds largest publisher of medical and scientific literature, forms part of the Reed Elsevier group. ... In human anatomy, the genitofemoral nerve originates from the upper part of the lumbar plexus of spinal nerves. ... The psoas major is a muscle of the human abdomen. ... Male Anatomy The spermatic cord is the name given to the cord-like structure formed by the vas deferens and surrounding tissue (veins, arteries, nerves, and lymphatic vessels) that run from the abdomen down to each testicle. ...

Lumbosacral plexus

lumbar plexus: iliohypogastric - ilioinguinal - genitofemoral (femoral branch/lumboinguinal, genital branch) - lateral cutaneous of thigh (patellar) - obturator (accessory obturator) - femoral (saphenous) The anterior divisions of the lumbar nerve, sacral nerve, and coccygeal nerves form the lumbosacral plexus, the first lumbar nerve being frequently joined by a branch from the twelfth thoracic. ... Grays Fig. ... The Iliohypogastric Nerve arises from the first lumbar nerve. ... The Ilioinguinal Nerve, smaller than the Iliohypogastric nerve, arises with it from the first lumbar nerve. ... In human anatomy, the genitofemoral nerve originates from the upper part of the lumbar plexus of spinal nerves. ... The Obturator Nerve arises from the ventral divisions of the second, third, and fourth lumbar nerves; the branch from the third is the largest, while that from the second is often very small. ... The Femoral Nerve supplies innervation the anterior portion of the leg. ...


sacral/coccygeal plexus: to quadratus femoris - to obturator internus - to the piriformis - superior gluteal - inferior gluteal - posterior cutaneous of thigh
sciatic: tibial (sural - medial plantar - lateral plantar) - common fibular (deep fibular - superficial fibular) In human anatomy, the Sacral plexus refers to the nerve plexus emerging from the sacral vertebrae (S1-S4), and which provides nerves for the pelvis and lower limbs. ... The nerve to quadratus femoris is a nerve that provides innervation to the quadratus femoris and gemellus inferior muscles. ... The superior gluteal nerve is a nerve that originates in the pelvis which supplies the gluteus medius, the gluteus minimus, and the tensor fasciae latae muscles. ... The Superior Gluteal Nerve () arises from the dorsal divisions of the fourth and fifth lumbar and first sacral nerves: it leaves the pelvis through the greater sciatic foramen above the Piriformis, accompanied by the superior gluteal vessels, and divides into a superior and an inferior branch. ... This article or section may be confusing or unclear for some readers, and should be edited to rectify this. ... The Tibial Nerve The tibial nerve passes through the popliteal fossa to pass below the arch of soleus. ... The sural nerve (short saphenous nerve), formed by the junction of the medial sural cutaneous with the peroneal anastomotic branch, passes downward near the lateral margin of the tendo calcaneus, lying close to the small saphenous vein, to the interval between the lateral malleolus and the calcaneus. ...


pudendal plexus: perforating cutaneous - pudendal (dorsal of the penis/clitoris, inferior anal, perineal and posterior scrotal/labial) - anococcygeal The pudendal plexus is not sharply marked off from the sacral plexus, and as a consequence some of the branches which spring from it may arise in conjunction with those of the sacral plexus. ... The Perforating Cutaneous Nerve usually arises from the posterior surface of the second and third sacral nerves. ... The pudendal nerve is responsible for orgasm, urination, and defecation in both sexes. ... The dorsal nerve of the clitoris is a nerve in females that branches off the pudendal nerve to innervate the clitoris. ... Anococcygeal Nerves: The fifth sacral nerve receives a communicating filament from the fourth, and unites with the coccygeal nerve to form the coccygeal plexus. ...
