Peroneal Artery
In anatomy, the fibular artery, also known as the peroneal artery, supplies blood to the lateral compartment of the leg. It arises from the tibial-fibular trunk. Structure The fibular artery arises from the bifurcation of tibial-fibular trunk into the fibular and posterior tibial arteries in the upper part of the leg proper, just below the knee. It runs towards the foot in the deep posterior compartment of the leg, just medial to the fibula. It supplies a perforating branch to both the lateral and anterior compartments of the leg; it also provides a nutrient artery to the fibula. Some sources claim that the fibular artery arises directly from the posterior tibial artery, but vascular and plastic surgeons note the clinical significance of the tibial-fibular trunk. The fibular artery is accompanied by small veins (venae comitantes) known as fibular veins. Branches Communication branch to posterior tibial artery. Perforating branch to anterior lateral malleolar artery. A ca ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tibial-fibular Trunk
Tibiofibular trunk (or tibioperoneal trunk) is an arterial trunk representing the direct continuation of the popliteal artery distal to where the anterior tibial artery (the first branch of the popliteal artery) branches off from it. The tibiofibular trunk terminates by bifurcating into two terminal branches: the posterior tibial artery, and the fibular artery In anatomy, the fibular artery, also known as the peroneal artery, supplies blood to the lateral compartment of the leg. It arises from the tibial-fibular trunk. Structure The fibular artery arises from the bifurcation of tibial-fibular trunk .... This is the most common configuration of the origins of these arteries, however, many other anatomical variations exist. The vessel here described as the tibiofibular trunk may alternately be regarded as the initial portion of the posterior tibial artery, with the fibular artery instead regarded as its branch.

Venae Comitantes
Vena comitans (Latin for accompanying vein, also known as a satellite vein) refers to a vein that is usually paired, with both veins lying on the sides of an artery. Because they are generally found in pairs, they are often referred to by their plural form: venae comitantes. Venae comitantes are usually found with certain smaller arteries, especially those in the extremities. Larger arteries, on the other hand, generally do not have venae comitantes. They usually have a single, similarly sized vein which is not as intimately associated with the artery. Function As the vein is found in close proximity to an artery the pulsations of the artery aid venous return. Claude Bernard suggested the interchange of heat between the arteries and adjacent veins might moderate cooling of the arterial blood, for which there is experimental evidence. Examples Examples of arteries and their venae comitantes: * Radial artery and radial veins * Ulnar artery and ulnar veins * Brachial artery a ...

Tibial Nerve
The tibial nerve is a branch of the sciatic nerve. The tibial nerve passes through the popliteal fossa to pass below the arch of soleus. Structure Popliteal fossa The tibial nerve is the larger terminal branch of the sciatic nerve with root values of L4, L5, S1, S2, and S3. It lies superficial (or posterior) to the popliteal vessels, extending from the superior angle to the inferior angle of the popliteal fossa, crossing the popliteal vessels from lateral to medial side. It gives off branches as shown below: * Muscular branches - Muscular branches arise from the distal part of the popliteal fossa. It supplies the medial and lateral heads of gastrocnemius, soleus, plantaris and popliteus muscles. Nerve to popliteus crosses the popliteus muscle, runs downwards and laterally, winds around the lower border of the popliteus to supply the deep (or anterior) surface of the popliteus. This nerve also supplies the tibialis posterior muscle, superior tibiofibular joint, tibia bone, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tibialis Anterior
The tibialis anterior muscle is a muscle of the anterior compartment of the lower leg. It originates from the upper portion of the tibia; it inserts into the medial cuneiform and first metatarsal bones of the foot. It acts to dorsiflex and invert the foot. This muscle is mostly located near the shin. It is situated on the lateral side of the tibia; it is thick and fleshy above, tendinous below. The tibialis anterior overlaps the anterior tibial vessels and deep peroneal nerve in the upper part of the leg. Structure The tibialis anterior muscle is the most medial muscle of the anterior compartment of the leg. The muscle ends in a tendon which is apparent on the anteriomedial dorsal aspect of the foot close to the ankle. Its tendon is ensheathed in a synovial sheath. The tendon passes through the medial compartment superior and inferior extensor retinacula of the foot. Origin The tibialis anterior muscle arises from the upper 2/3 of the lateral surface of the tibia and the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Calcaneus
In humans and many other primates, the calcaneus (; from the Latin ''calcaneus'' or ''calcaneum'', meaning heel; : calcanei or calcanea) or heel bone is a bone of the Tarsus (skeleton), tarsus of the foot which constitutes the heel. In some other animals, it is the point of the hock (anatomy), hock. Structure In humans, the calcaneus is the largest of the tarsal bones and the largest bone of the foot. Its long axis is pointed forwards and laterally. The talus bone, calcaneus, and navicular bone are considered the proximal row of tarsal bones. In the calcaneus, several important structures can be distinguished:Platzer (2004), p 216 There is a large calcaneal tuberosity located posteriorly on plantar surface with medial and lateral tubercles on its surface. Besides, there is another peroneal tubercle on its lateral surface. On its lower edge on either side are its lateral and medial processes (serving as the origins of the Abductor hallucis muscle, abductor hallucis and Abductor di ...

Anterior Lateral Malleolar Artery
The anterior lateral malleolar artery (lateral anterior malleolar artery, external malleolar artery) is an artery in the ankle. The anterior lateral malleolar artery is a branch of the anterior tibial artery. It passes beneath the tendons of the extensor digitorum longus and fibularis tertius and supplies the lateral side of the ankle. It forms anastomoses with the perforating branch of the fibular artery In anatomy, the fibular artery, also known as the peroneal artery, supplies blood to the lateral compartment of the leg. It arises from the tibial-fibular trunk. Structure The fibular artery arises from the bifurcation of tibial-fibular trunk ..., and with ascending twigs from the lateral tarsal artery.

Fibular Veins
In anatomy, the fibular veins (also known as peroneal veins) are accompanying veins (venae comitantes) of the fibular artery. Structure The fibular veins are deep veins that help carry blood from the lateral compartment of the leg. They drain into the posterior tibial veins, which in turn drain into the popliteal vein. The fibular veins accompany the fibular artery. See also * Fibular artery * Common fibular nerve * Venae comitantes Additional images File:Gray440_color.png, Cross-section through middle of leg.

Fibula
The fibula (: fibulae or fibulas) or calf bone is a leg bone on the lateral side of the tibia, to which it is connected above and below. It is the smaller of the two bones and, in proportion to its length, the most slender of all the long bones. Its upper extremity is small, placed toward the back of the head of the tibia, below the knee joint and excluded from the formation of this joint. Its lower extremity inclines a little forward, so as to be on a plane anterior to that of the upper end; it projects below the tibia and forms the lateral part of the ankle joint. Structure The bone has the following components: * Lateral malleolus * Interosseous membrane connecting the fibula to the tibia, forming a syndesmosis joint * The superior tibiofibular articulation is an arthrodial joint between the lateral condyle of the tibia and the head of the fibula. * The inferior tibiofibular articulation (tibiofibular syndesmosis) is formed by the rough, convex surface of the medial si ...

Popliteal Artery
The popliteal artery is a deeply placed continuation of the femoral artery opening in the distal portion of the adductor magnus muscle. It courses through the popliteal fossa and ends at the lower border of the popliteus muscle, where it branches into the anterior and posterior tibial arteries. The deepest (most anterior) structure in the fossa, the popliteal artery runs close to the joint capsule of the knee as it spans the intercondylar fossa. Five genicular branches of the popliteal artery supply the capsule and ligaments of the knee joint. The genicular arteries are the superior lateral, superior medial, middle, inferior lateral, and inferior medial genicular arteries. They participate in the formation of the periarticular genicular anastomosis, a network of vessels surrounding the knee that provides collateral circulation capable of maintaining blood supply to the leg during full knee flexion, which may kink the popliteal artery.

Anatomy
Anatomy () is the branch of morphology concerned with the study of the internal structure of organisms and their parts. Anatomy is a branch of natural science that deals with the structural organization of living things. It is an old science, having its beginnings in prehistoric times. Anatomy is inherently tied to developmental biology, embryology, comparative anatomy, evolutionary biology, and phylogeny, as these are the processes by which anatomy is generated, both over immediate and long-term timescales. Anatomy and physiology, which study the structure and function of organisms and their parts respectively, make a natural pair of related disciplines, and are often studied together. Human anatomy is one of the essential basic sciences that are applied in medicine, and is often studied alongside physiology. Anatomy is a complex and dynamic field that is constantly evolving as discoveries are made. In recent years, there has been a significant increase in the use of ...
