Arcuate Artery Of The Foot
The arcuate artery of the foot (metatarsal artery) arises from dorsalis pedis slightly anterior to the lateral tarsal artery, specifically over the naviculocuneiform joint; it passes lateralward, over the bases of the lateral four metatarsal bones, beneath the tendons of the extensor digitorum brevis, its direction being influenced by its point of origin; and it terminates in the lateral tarsal artery. It communicates with the plantar arteries through the perforating arteries of the foot. It runs with the lateral terminal branch of deep fibular nerve. This vessel gives off the second, third, and fourth dorsal metatarsal arteries The arcuate artery of the foot gives off the second, third, and fourth dorsal metatarsal arteries, which run forward upon the corresponding Interossei dorsales; in the clefts between the toes, each divides into two dorsal digital branches for the ....

Anterior Tibial Artery
The anterior tibial artery is an artery of the leg. It carries blood to the anterior compartment of the leg and dorsum (biology), dorsal surface of the foot, from the popliteal artery. Structure Course The anterior tibial artery is a branch of the popliteal artery. It originates at the distal end of the popliteus muscle posterior to the tibia. The artery typically passes anterior to the popliteus muscle prior to passing between the tibia and fibula through an oval opening at the superior aspect of the interosseus membrane. The artery then descends between the tibialis anterior and extensor digitorum longus muscles. It is accompanied by the anterior tibial vein, and the deep peroneal nerve, along its course. It crosses the anterior aspect of the ankle joint, at which point it becomes the dorsalis pedis artery. Branches The branches of the anterior tibial artery are: *posterior tibial recurrent artery *anterior tibial recurrent artery *muscular branches *anterior medial malleo ...

Dorsalis Pedis Artery
In human anatomy, the dorsalis pedis artery (dorsal artery of foot) is a blood vessel of the lower limb. It arises from the anterior tibial artery, and ends at the first intermetatarsal space (as the first dorsal metatarsal artery and the deep plantar artery). It carries oxygenated blood to the dorsal side of the foot. It is useful for taking a pulse. It is also at risk during anaesthesia of the deep peroneal nerve. Structure The dorsalis pedis artery is located 1/3 from medial malleolus of the ankle. It arises at the anterior aspect of the ankle joint and is a continuation of the anterior tibial artery. It ends at the proximal part of the first intermetatarsal space. Here, it divides into two branches, the first dorsal metatarsal artery, and the deep plantar artery. It is covered by skin and fascia, but is fairly superficial. The dorsalis pedis communicates with the plantar blood supply of the foot through the deep plantar artery. Along its course, it is accompanied by a deep ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Human Leg
The human leg, in the general word sense, is the entire lower limb (anatomy), limb of the human body, including the foot, thigh or sometimes even the hip or Gluteal muscles, gluteal region. However, the definition in human anatomy refers only to the section of the lower limb extending from the knee to the ankle, also known as the crus or, especially in non-technical use, the shank. Legs are used for standing, and all forms of locomotion including recreational such as dancing, and constitute a significant portion of a person's mass. Female legs generally have greater hip anteversion and tibiofemoral angles, but shorter femur and tibial lengths than those in males. Structure In human anatomy, the lower leg is the part of the lower limb that lies between the knee and the ankle. Anatomists restrict the term ''leg'' to this use, rather than to the entire lower limb. The thigh is between the hip and knee and makes up the rest of the lower limb. The term ''lower limb'' or ''lower extre ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arteria Dorsalis Pedis
In human anatomy, the dorsalis pedis artery (dorsal artery of foot) is a blood vessel of the lower limb. It arises from the anterior tibial artery, and ends at the first intermetatarsal space (as the first dorsal metatarsal artery and the deep plantar artery). It carries oxygenated blood to the Dorsum (biology), dorsal side of the foot. It is useful for taking a pulse. It is also at risk during Anesthesia, anaesthesia of the deep peroneal nerve. Structure The dorsalis pedis artery is located 1/3 from malleolus, medial malleolus of the ankle. It arises at the anterior aspect of the ankle joint and is a continuation of the anterior tibial artery. It ends at the proximal part of the first intermetatarsal space. Here, it divides into two branches, the first dorsal metatarsal artery, and the deep plantar artery. It is covered by skin and fascia, but is fairly superficial. The dorsalis pedis communicates with the plantar blood supply of the foot through the deep plantar artery. Along ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dorsal Metatarsal Arteries
The arcuate artery of the foot gives off the second, third, and fourth dorsal metatarsal arteries, which run forward upon the corresponding Interossei dorsales; in the clefts between the toes, each divides into two dorsal digital branches for the adjoining toes. At the proximal parts of the interosseous spaces these vessels receive the posterior perforating branches from the plantar arch, and at the distal parts of the spaces they are joined by the anterior perforating branches, from the plantar metatarsal arteries. The fourth dorsal metatarsal artery gives off a branch which supplies the lateral side of the fifth toe. The first dorsal metatarsal artery runs forward on the first Interosseous dorsalis In human anatomy, the dorsal interossei (DI) are four muscles in the back of the hand that act to abduct (spread) the index, middle, and ring fingers away from hand's midline (ray of middle finger) and assist in flexion at the metacarpophalangea ....

Dorsal Venous Arch Of The Foot
The dorsal venous arch of the foot is a superficial vein that connects the small saphenous vein and the great saphenous vein. Anatomically, it is defined by where the dorsal veins of the first and fifth digit Digit may refer to: Mathematics and science * Numerical digit, as used in mathematics or computer science ** Hindu-Arabic numerals, the most common modern representation of numerical digits * Digit (anatomy), the most distal part of a limb, such ..., respectively, meet the great saphenous vein and small saphenous vein. It is usually fairly easy to palpate and visualize (if the patient is barefoot). It lies superior to the metatarsal bones approximately midway between the ankle joint and metatarsal phalangeal joints. Additional images File:Slide3Bubu.JPG, Dorsum of Foot. Ankle joint.

Lateral Tarsal Artery
The lateral tarsal artery (tarsal artery) arises from the dorsalis pedis, as that vessel crosses the navicular bone; it passes in an arched direction lateralward, lying upon the tarsal bones, and covered by extensor hallucis brevis and extensor digitorum brevis; it supplies these muscles and the articulations of the tarsus, and receives the arcuate over the base of the fifth metatarsal. It may receive contributions from branches of the anterior lateral malleolar and the perforating branch of the peroneal artery directed towards the joint capsule, and from the lateral plantar arteries through perforating arteries of the foot.

Metatarsal
The metatarsal bones, or metatarsus, are a group of five long bones in the foot, located between the tarsal bones of the hind- and mid-foot and the phalanges of the toes. Lacking individual names, the metatarsal bones are numbered from the medial side (the side of the great toe): the first, second, third, fourth, and fifth metatarsal (often depicted with Roman numerals). The metatarsals are analogous to the metacarpal bones of the hand. The lengths of the metatarsal bones in humans are, in descending order, second, third, fourth, fifth, and first. Structure The five metatarsals are dorsal convex long bones consisting of a shaft or body, a base (proximally), and a head (distally).Platzer 2004, p. 220 The body is prismoid in form, tapers gradually from the tarsal to the phalangeal extremity, and is curved longitudinally, so as to be concave below, slightly convex above. The base or posterior extremity is wedge-shaped, articulating proximally with the tarsal bones, and by it ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Extensor Digitorum Brevis
The extensor digitorum brevis muscle (sometimes EDB) is a muscle on the upper surface of the foot that helps extend digits 2 through 4. Structure The muscle originates from the forepart of the upper and lateral surface of the calcaneus (in front of the groove for the peroneus brevis tendon), from the interosseous talocalcaneal ligament and the stem of the inferior extensor retinaculum. The fibres pass obliquely forwards and medially across the dorsum of the foot and end in four tendons. The medial part of the muscle, also known as extensor hallucis brevis, ends in a tendon which crosses the dorsalis pedis artery and inserts into the dorsal surface of the base of the proximal phalanx of the great toe. The other three tendons insert into the lateral sides of the tendons of extensor digitorum longus for the second, third and fourth toes.

Lateral Terminal Branch Of Deep Fibular 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 ante ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
