Medial Dorsal Cutaneous Nerve
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. It also supplies the integument of the medial side of the foot and ankle, and communicates with the saphenous nerve, and with the deep peroneal nerve The deep fibular nerve (also known as deep peroneal nerve) begins at the bifurcation of the common fibular nerve between the fibula and upper part of the fibularis longus, passes infero-medially, deep to the extensor digitorum longus, to the anter ....

Superficial Fibular Nerve
The superficial fibular nerve (also known as superficial peroneal nerve) innervates the fibularis longus and fibularis 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 fibular nerve). Structure Lateral side of the leg The superficial fibular nerve is the main nerve of the lateral compartment of the leg. It begins at the lateral side of the neck of fibula, and runs through the fibularis longus and fibularis brevis muscles. In the middle third of the leg, it descends between the fibularis longus and fibularis brevis, and then reaches the anterior border of the fibularis brevis to enter the groove between the fibularis brevis and the extensor digitorum longus under the deep fascia of leg. It becomes superficial at the junction of upper two-thirds and lower one-thirds of the leg by piercing the deep fascia. The superficial fibular ner ...

Ankle-joint
The ankle, or the talocrural region, or the jumping bone (informal) is the area where the foot and the leg meet. The ankle includes three joints: the ankle joint proper or talocrural joint, the subtalar joint, and the inferior tibiofibular joint. The movements produced at this joint are dorsiflexion and plantarflexion of the foot. In common usage, the term ankle refers exclusively to the ankle region. In medical terminology, "ankle" (without qualifiers) can refer broadly to the region or specifically to the talocrural joint. The main bones of the ankle region are the talus (in the foot), and the tibia and fibula (in the leg). The talocrural joint is a synovial hinge joint that connects the distal ends of the tibia and fibula in the lower limb with the proximal end of the talus. The articulation between the tibia and the talus bears more weight than that between the smaller fibula and the talus.

Dorsum (biology)
Standard anatomical terms of location are used to unambiguously describe the anatomy of animals, including humans. The terms, typically derived from Latin or Greek roots, describe something in its standard anatomical position. This position provides a definition of what is at the front ("anterior"), behind ("posterior") and so on. As part of defining and describing terms, the body is described through the use of anatomical planes and anatomical axes. The meaning of terms that are used can change depending on whether an organism is bipedal or quadrupedal. Additionally, for some animals such as invertebrates, some terms may not have any meaning at all; for example, an animal that is radially symmetrical will have no anterior surface, but can still have a description that a part is close to the middle ("proximal") or further from the middle ("distal"). International organisations have determined vocabularies that are often used as standard vocabularies for subdisciplines of an ...

Great Toe
Toes are the digits (fingers) of the foot of a tetrapod. Animal species such as cats that walk on their toes are described as being ''digitigrade''. Humans, and other animals that walk on the soles of their feet, are described as being ''plantigrade''; '' unguligrade'' animals are those that walk on hooves at the tips of their toes. Structure There are normally five toes present on each human foot. Each toe consists of three phalanx bones, the proximal, middle, and distal, with the exception of the big toe ( la, hallux). For a minority of people, the little toe also is missing a middle bone. The hallux only contains two phalanx bones, the proximal and distal. The joints between each phalanx are the interphalangeal joints. The proximal phalanx bone of each toe articulates with the metatarsal bone of the foot at the metatarsophalangeal joint. Each toe is surrounded by skin, and present on all five toes is a toenail. The toes are, from medial to lateral: * the first toe, ...

Foot
The foot ( : feet) is an anatomical structure found in many vertebrates. It is the terminal portion of a limb which bears weight and allows locomotion. In many animals with feet, the foot is a separate organ at the terminal part of the leg made up of one or more segments or bones, generally including claws or nails. Etymology The word "foot", in the sense of meaning the "terminal part of the leg of a vertebrate animal" comes from "Old English fot "foot," from Proto-Germanic *fot (source also of Old Frisian fot, Old Saxon fot, Old Norse fotr, Danish fod, Swedish fot, Dutch voet, Old High German fuoz, German Fuß, Gothic fotus "foot"), from PIE root *ped- "foot". The "plural form feet is an instance of i-mutation." Structure The human foot is a strong and complex mechanical structure containing 26 bones, 33 joints (20 of which are actively articulated), and more than a hundred muscles, tendons, and ligaments.Podiatry Channel, ''Anatomy of the foot and ankle'' The joints of ...

Saphenous Nerve
The saphenous nerve (long or internal saphenous nerve) is the largest cutaneous branch of the femoral nerve. It is a strictly sensory nerve, and has no motor function. Structure It is purely a sensory nerve. The saphenous nerve is the largest and terminal branch of the femoral nerve. Shortly after the femoral nerve passes under the inguinal ligament, it splits into anterior and posterior divisions by the passage of the lateral femoral circumflex artery (a branch of the profunda femoris artery). The posterior division then gives off the saphenous nerve as it converges with the femoral artery where it passes beneath the sartorius muscle. The saphenous nerve lies in front of the femoral artery, behind the aponeurotic covering of the adductor canal, as far as the opening in the lower part of the adductor magnus muscle. There it diverges from the artery, and emerges from behind the lower edge of the aponeurotic covering of the canal. It descends vertically along the medial side of t ...

Deep Peroneal Nerve
The deep fibular nerve (also known as deep peroneal nerve) begins at the bifurcation of the common fibular nerve between the fibula and upper part of the fibularis longus, passes infero-medially, deep to the 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''. Structure Lateral side of the leg The deep fibular nerve is the nerve of the anterior compartment of the leg and the dorsum of the foot. It is one of the terminal branches of the common fibular nerve. It corresponds to the posterior interosseus nerve of the forearm. It begins at the lateral side of the fibula bone, and then enters the anterior compartment by piercing the anterior intermuscular septum. It then pierces the extensor digitorum longus and lies next to the anterior ti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
