Branches

The saphenous nerve, about the middle of the thigh, gives off a branch which joins the subsartorial plexus.


At the medial side of the knee it gives off a large infrapatellar branch, which pierces the Sartorius and fascia lata, and is distributed to the skin in front of the patella. For the muscle, see sartorius muscle. ... The deep fascia of the thigh is named, from its great extent, the fascia lata; it constitutes an investment for the whole of this region of the limb, but varies in thickness in different parts. ... The patella or kneecap is a thick, triangular bone which articulates with the femur and covers and protects the front of the knee joint. ...


This nerve communicates above the knee with the anterior cutaneous branches of the femoral nerve; below the knee, with other branches of the saphenous; and, on the lateral side of the joint, with branches of the lateral femoral cutaneous nerve, forming a plexiform net-work, the plexus patellae. The Femoral Nerve supplies innervation the anterior portion of the leg. ... The Lateral Femoral Cutaneous Nerve (external cutaneous nerve) arises from the dorsal divisions of the second and third lumbar nerves. ...


The infrapatellar branch is occasionally small, and ends by joining the anterior cutaneous branches of the femoral, which supply its place in front of the knee.


Below the knee, the branches of the saphenous nerve are distributed to the skin of the front and medial side of the leg, communicating with the cutaneous branches of the femoral, or with filaments from the obturator nerve. 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. ...

Lumbosacral plexus

lumbar plexus: iliohypogastric - ilioinguinal - genitofemoral (femoral branch/lumboinguinal, genital branch) - lateral cutaneous of thigh (patellar) - obturator (accessory obturator) - femoral (saphenous) - lumbosacral trunk 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 lumboinguinal nerve (femoral or crural branch of genitofemoral) descends on the external iliac artery, sending a few filaments around it, and, passing beneath the inguinal ligament, enters the sheath of the femoral vessels, lying superficial and lateral to the femoral artery. ... 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 lateral cutaneous nerve of the thigh (also called the lateral femoral cutaneous nerve) is a cutaneous nerve that innervates the skin on the lateral part of the thigh. ... The terminal filaments of the lateral femoral cutaneous nerve frequently communicate with the anterior cutaneous branches of the femoral nerve, and with the infrapatellar branch of the saphenous nerve, forming with them the patellar plexus. ... 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 Accessory Obturator Nerve is present in about 29 per cent. ... The Femoral Nerve supplies innervation the anterior portion of the leg. ... The lumbosacral trunk is nervous tissue that connects the lumbar plexus with the sacral plexus. ...


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 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. ... 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 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. ... The medial plantar nerve (internal plantar nerve), the larger of the two terminal divisions of the tibial nerve, accompanies the medial plantar artery. ... The Lateral Plantar Nerve (external plantar nerve) 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 common peroneal nerve (common fibular nerve; external popliteal nerve; peroneal nerve), about one-half the size of the tibial nerve, is derived from the dorsal branches of the fourth and fifth lumbar and the first and second sacral nerves. ... The Deep fibular nerve (deep peroneal nerve) begins at the bifurcation of the common peroneal nerve, between the fibula and upper part of the Fibularis (Peronæus) longus, passes infero-medially, deep to Extensor digitorum longus, to the anterior surface of the interosseous membrane, and comes into relation with the...


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. ... The Inferior rectal nerves (inferior anal nerves, inferior hemorrhoidal nerve) occasionally arises directly from the sacral plexus; it crosses the ischiorectal fossa, with the inferior hemorrhoidal vessels, toward the anal canal and the lower end of the rectum, and is distributed to the Sphincter ani externus and to the integument... The perineal nerve is a nerve arising from the pudendal nerve that supplies the perineum. ... The posterior scrotal (or labial) branches; superficial peroneal nerves) are two in number, medial and lateral. ...
