Fibular Vein
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.

Posterior Tibial Vein
The posterior tibial veins are veins of the leg in humans. They drain the posterior compartment of the leg and the plantar surface of the foot to the popliteal vein. Structure The posterior tibial veins receive blood from the medial and lateral plantar veins. They drain the posterior compartment of the leg and the plantar surface of the foot to the popliteal vein, which it forms when it joins with the anterior tibial vein. The posterior tibial vein is accompanied by an homonym artery, the posterior tibial artery, along its course. It lies posterior to the medial malleolus in the ankle. They receive the most important perforator vein Perforator veins are so called because they perforate the deep fascia of muscles, to connect the superficial veins to the deep veins where they drain. Perforator veins play an essential role in maintaining normal blood draining. They have valves ...s: the Cockett perforators, superior, medial and inferior. Additional images File:Gray440_col ...

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 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 calcan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Anatomy
Anatomy () is the branch of biology concerned with the study of the 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 (biology), 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 research, basic sciences that are applied in medicine. The discipline of anatomy is divided into macroscopic scale, macroscopic and microscopic scale, microscopic. Gross anatomy, Macroscopic anatomy, or gross anatomy, is the examination of an ...

Venae Comitantes
Vena comitans is Latin for accompanying vein. It refers to a vein that is usually paired, with both veins lying on the sides of an artery. They are found in close proximity to arteries so that the pulsations of the artery aid venous return. 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. Examples of arteries and their venae comitantes: * Radial artery and radial veins * Ulnar artery and ulnar veins * Brachial artery and brachial veins * Anterior tibial artery and anterior tibial veins * Posterior tibial artery and Posterior tibial veins * Fibular artery and Fibular veins Examples of arteries that do not have venae comitantes (i.e. thos ...

Deep Veins
A deep vein is a vein that is deep in the body. This contrasts with superficial veins that are close to the body's surface. Deep veins are almost always beside an artery with the same name (e.g. the femoral vein is beside the femoral artery). Collectively, they carry the vast majority of the blood. Occlusion of a deep vein can be life-threatening and is most often caused by thrombosis. Occlusion of a deep vein by thrombosis is called ''deep vein thrombosis''. Because of their location deep within the body, operation on these veins can be difficult.

Lateral Compartment Of The Leg
The lateral compartment of the leg is a fascial compartment of the lower leg. It contains muscles which make eversion and plantarflexion of the foot. Muscles The lateral compartment of the leg contains: * Fibularis longus * Fibularis brevis Action * Foot evertors * Foot plantarflexion Nerve Supply The lateral compartment of the leg is supplied by the superficial fibular nerve (superficial peroneal nerve). Blood Supply Its proximal and distal arterial supply consists of perforating branches of the anterior tibial artery and fibular artery. Additional images File:Lateral compartment of leg - animation.gif, Animation. Fibularis longus (blue) and fibularis brevis (red).

Popliteal Vein
The popliteal vein is a vein of the lower limb. It is formed from the anterior tibial vein and the posterior tibial vein. It travels medial to the popliteal artery, and becomes the femoral vein. It drains blood from the leg. It can be assessed using medical ultrasound. It can be affected by popliteal vein entrapment. Structure The popliteal vein is formed by the junction of the venae comitantes of the anterior tibial vein and the posterior tibial vein at the lower border of the popliteus muscle. It travels on the medial side of the popliteal artery. It is superficial to the popliteal artery. As it ascends through the fossa, it crosses behind the popliteal artery so that it comes to lie on its lateral side. It passes through the adductor hiatus (the opening in the adductor magnus muscle) to become the femoral vein.Moore K.L. and Dalley A.F.

Common Fibular Nerve
The common fibular nerve (also known as the common peroneal nerve, external popliteal nerve, or lateral popliteal nerve) is a nerve in the lower leg that provides sensation over the posterolateral part of the leg and the knee joint. It divides at the knee into two terminal branches: the superficial fibular nerve and deep fibular nerve, which innervate the muscles of the lateral and anterior compartments of the leg respectively. When the common fibular nerve is damaged or compressed, foot drop can ensue. Structure The common fibular nerve is the smaller terminal branch of the sciatic nerve. The common fibular nerve has root values of L4, L5, S1, and S2. It arises from the superior angle of the popliteal fossa and extends to the lateral angle of the popliteal fossa, along the medial border of the biceps femoris. It then winds around the neck of the fibula to pierce the fibularis longus and divides into terminal branches of the superficial fibular nerve and the deep fibular nerve. Bef ...

Coronal Plane
The coronal plane (also known as the frontal plane) is an anatomical plane that divides the body into dorsal and ventral sections. It is perpendicular to the sagittal and transverse planes. Details The coronal plane is an example of a longitudinal plane. For a human, the mid-coronal plane would transect a standing body into two halves (front and back, or anterior and posterior) in an imaginary line that cuts through both shoulders. The description of the coronal plane applies to most animals as well as humans even though humans walk upright and the various planes are usually shown in the vertical orientation. The sternal plane (''planum sternale'') is a coronal plane which transects the front of the sternum. Etymology The term is derived from Latin ''corona'' ('garland, crown'), from Ancient Greek κορώνη (''korōnē'', 'garland, wreath'). The coronal plane is so-called because it lies in the direction of Coronal suture. Additional images File:Coronal plane CT scan of t ...
