Nerve: Medial plantar nerve
The plantar nerves.
Latin n. plantaris medialis
Gray's subject #213 963
From tibial nerve
Dorlands/Elsevier n_05/12566532

The medial plantar nerve (internal plantar nerve), the larger of the two terminal divisions of the tibial nerve, accompanies the medial plantar artery. Latin is an ancient Indo-European language originally spoken in Latium, the region immediately surrounding Rome. ... The Tibial Nerve The tibial nerve passes through the popliteal fossa to pass below the arch of soleus. ... Elseviers logo Elsevier, the worlds largest publisher of medical and scientific literature, forms part of the Reed Elsevier group. ... The Tibial Nerve The tibial nerve passes through the popliteal fossa to pass below the arch of soleus. ... The medial plantar artery (internal plantar artery), much smaller than the lateral, passes forward along the medial side of the foot. ...


From its origin under the laciniate ligament it passes under cover of the Abductor hallucis, and, appearing between this muscle and the Flexor digitorum brevis, gives off a proper digital plantar nerve and finally divides opposite the bases of the metatarsal bones into three common digital plantar nerves. The metatarsus consists of the five long bones of the foot, which are numbered from the medial side (ossa metatarsalia I.-V.); each presents for examination a body and two extremities. ...

Branches

The branches of the medial plantar nerve are: (1) cutaneous, (2) muscular, (3) articular, (4) a proper digital nerve to the medial side of the great toe, and (5) three common digital nerves.


Cutaneous branches

The cutaneous branches pierce the plantar aponeurosis between the Abductor hallucis and the Flexor digitorum brevis and are distributed to the skin of the sole of the foot. Aponeuroses (απο, away, and νευρον, a sinew) are membranes separating muscles from each other. ...


Muscular branches

The muscular branches supply the Abductor hallucis, the Flexor digitorum brevis, the Flexor hallucis brevis, and the first Lumbricalis; those for the Abductor hallucis and Flexor digitorum brevis arise from the trunk of the nerve near its origin and enter the deep surfaces of the muscles; the branch of the Flexor hallucis brevis springs from the proper digital nerve to the medial side of the great toe, and that for the first Lumbricalis from the first common digital nerve. Lumbrical can refer to: Lumbrical muscle (hand) Lumbrical muscle (foot) Category: ...


Articular branches

The articular branches supply the articulations of the tarsus and metatarsus. Wikipedia does not yet have an article with this exact name. ... In tetrapods, the tarsi are the cluster of bones in the foot between the tibia and fibula and the metatarsus. ... The metatarsus consists of the five long bones of the foot, which are numbered from the medial side (ossa metatarsalia I.-V.); each presents for examination a body and two extremities. ...


Proper digital nerve of the great toe

The proper digital nerve of the great toe (nn. digitales plantares proprii; plantar digital branches) supplies the Flexor hallucis brevis and the skin on the medial side of the great toe.


Three common digital nerves

The three common digital nerves (nn. digitales plantares communes) pass between the divisions of the plantar aponeurosis, and each splits into two proper digital nerves—those of the first common digital nerve supply the adjacent sides of the great and second toes; those of the second, the adjacent sides of the second and third toes; and those of the third, the adjacent sides of the third and fourth toes.


The third common digital nerve receives a communicating branch from the lateral plantar nerve; the first gives a twig to the first Lumbricalis. Lumbrical can refer to: Lumbrical muscle (hand) Lumbrical muscle (foot) Category: ...


Each proper digital nerve gives off cutaneous and articular filaments; and opposite the last phalanx sends upward a dorsal branch, which supplies the structures around the nail, the continuation of the nerve being distributed to the ball of the toe.


It will be observed that these digital nerves are similar in their distribution to those of the median nerve in the hand. Diagram from Grays anatomy, depicting the peripheral nerves of the upper extremity, amongst others the median nerve The median nerve is a nerve that runs down the arm and forearm. ...

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 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 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. ... 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 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 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 posterior scrotal (or labial) branches; superficial peroneal nerves) are two in number, medial and lateral. ... Anococcygeal Nerves: The fifth sacral nerve receives a communicating filament from the fourth, and unites with the coccygeal nerve to form the coccygeal plexus. ...
