Fascia Cribrosa
The cribriform fascia, fascia cribrosa also Hesselbach's fascia is the portion of fascia covering the saphenous opening in the thigh. It is perforated by the great saphenous vein and by numerous blood and lymphatic vessels. (A structure in anatomy that is pierced by several small holes is referred to as ''cribriform'' from Latin ''cribrum'' meaning sieve). Clinical significance The cribriform fascia has been proposed for use in preventing new vascularization when surgery is performed at the join between the great saphenous vein and the femoral vein. Eponym When the eponym is used, it is named for Franz Kaspar Hesselbach Franz Kaspar Hesselbach (27 January 1759 – 24 July 1816) was a German surgeon and anatomist who was a native of Hammelburg.

Fascia
A fascia (; plural fasciae or fascias; adjective fascial; from Latin: "band") is a band or sheet of connective tissue, primarily collagen, beneath the skin that attaches to, stabilizes, encloses, and separates muscles and other internal organs. Fascia is classified by layer, as superficial fascia, deep fascia, and ''visceral'' or ''parietal'' fascia, or by its function and anatomical location. Like ligaments, aponeuroses, and tendons, fascia is made up of fibrous connective tissue containing closely packed bundles of collagen fibers oriented in a wavy pattern parallel to the direction of pull. Fascia is consequently flexible and able to resist great unidirectional tension forces until the wavy pattern of fibers has been straightened out by the pulling force. These collagen fibers are produced by fibroblasts located within the fascia. Fasciae are similar to ligaments and tendons as they have collagen as their major component. They differ in their location and function: ligam ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Saphenous Opening
In anatomy, the saphenous opening (saphenous hiatus, also fossa ovalis) is an oval opening in the upper mid part of the fascia lata of the thigh. It lies 3–4 cm below and lateral to the pubic tubercle and is about 3 cm long and 1.5 cm wide. Structure Just inferolateral to the pubic tubercle the fascia extends downwards forming an arched (falciform) margin of the lateral boundary of the opening. It is covered by a thin perforated part of the superficial fascia called the fascia cribrosa which is pierced by the great saphenous vein, the 3 superficial branches of the femoral artery(except superficial circumflex iliac artery, which pierces fascia lata lateral to the saphenous opening), and lymphatics. It transmits the great saphenous vein and other smaller vessels including the superficial epigastric artery and superficial external pudendal artery, as well as the femoral branch of the genitofemoral nerve. The fascia cribrosa, which is pierced by the structures pass ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Thigh
In human anatomy, the thigh is the area between the hip ( pelvis) and the knee. Anatomically, it is part of the lower limb. The single bone in the thigh is called the femur. This bone is very thick and strong (due to the high proportion of bone tissue), and forms a ball and socket joint at the hip, and a modified hinge joint at the knee. Structure Bones The femur is the only bone in the thigh and serves as an attachment site for all muscles in the thigh. The head of the femur articulates with the acetabulum in the pelvic bone forming the hip joint, while the distal part of the femur articulates with the tibia and patella forming the knee. By most measures, the femur is the strongest bone in the body. The femur is also the longest bone in the body. The femur is categorised as a long bone and comprises a diaphysis, the shaft (or body) and two epiphysis or extremities that articulate with adjacent bones in the hip and knee.

Great Saphenous Vein
The great saphenous vein (GSV, alternately "long saphenous vein"; ) is a large, subcutaneous, superficial vein of the leg. It is the longest vein in the body, running along the length of the lower limb, returning blood from the foot, leg and thigh to the deep femoral vein at the femoral triangle. Structure The great saphenous vein originates from where the dorsal vein of the big toe (the hallux) merges with the dorsal venous arch of the foot. After passing in front of the medial malleolus (where it often can be visualized and palpated), it runs up the medial side of the leg. At the knee, it runs over the posterior border of the medial epicondyle of the femur bone. In the proximal anterior thigh inferolateral to the pubic tubercle, the great saphenous vein dives down deep through the cribriform fascia of the saphenous opening to join the femoral vein. It forms an arch, the saphenous arch, to join the common femoral vein in the region of the femoral triangle at the sapheno-fe ...

Blood Vessel
The blood vessels are the components of the circulatory system that transport blood throughout the human body. These vessels transport blood cells, nutrients, and oxygen to the tissues of the body. They also take waste and carbon dioxide away from the tissues. Blood vessels are needed to sustain life, because all of the body's tissues rely on their functionality. There are five types of blood vessels: the arteries, which carry the blood away from the heart; the arterioles; the capillaries, where the exchange of water and chemicals between the blood and the tissues occurs; the venules; and the veins, which carry blood from the capillaries back towards the heart. The word ''vascular'', meaning relating to the blood vessels, is derived from the Latin ''vas'', meaning vessel. Some structures – such as cartilage, the epithelium, and the lens and cornea of the eye – do not contain blood vessels and are labeled ''avascular''.

Lymphatic Vessel
The lymphatic vessels (or lymph vessels or lymphatics) are thin-walled vessels (tubes), structured like blood vessels, that carry lymph. As part of the lymphatic system, lymph vessels are complementary to the cardiovascular system. Lymph vessels are lined by endothelial cells, and have a thin layer of smooth muscle, and adventitia that binds the lymph vessels to the surrounding tissue. Lymph vessels are devoted to the propulsion of the lymph from the lymph capillaries, which are mainly concerned with the absorption of interstitial fluid from the tissues. Lymph capillaries are slightly bigger than their counterpart capillaries of the vascular system. Lymph vessels that carry lymph to a lymph node are called afferent lymph vessels, and those that carry it from a lymph node are called efferent lymph vessels, from where the lymph may travel to another lymph node, may be returned to a vein, or may travel to a larger lymph duct. Lymph ducts drain the lymph into one of the subc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Latin
Latin (, or , ) is a classical language belonging to the Italic branch of the Indo-European languages. Latin was originally a dialect spoken in the lower Tiber area (then known as Latium) around present-day Rome, but through the power of the Roman Republic it became the dominant language in the Italian region and subsequently throughout the Roman Empire. Even after the fall of Western Rome, Latin remained the common language of international communication, science, scholarship and academia in Europe until well into the 18th century, when other regional vernaculars (including its own descendants, the Romance languages) supplanted it in common academic and political usage, and it eventually became a dead language in the modern linguistic definition. Latin is a highly inflected language, with three distinct genders (masculine, feminine, and neuter), six or seven noun cases (nominative, accusative, genitive, dative, ablative, and vocative), five declensions, four verb conjug ...

Neovascularization
Neovascularization is the natural formation of new blood vessels ('' neo-'' + '' vascular'' + '' -ization''), usually in the form of functional microvascular networks, capable of perfusion by red blood cells, that form to serve as collateral circulation in response to local poor perfusion or ischemia. Growth factors that inhibit neovascularization include those that affect endothelial cell division and differentiation. These growth factors often act in a paracrine or autocrine fashion; they include fibroblast growth factor, placental growth factor, insulin-like growth factor, hepatocyte growth factor, and platelet-derived endothelial growth factor. There are three different pathways that comprise neovascularization:(1) vasculogenesis,(2) angiogenesis, and (3) arteriogenesis. Three pathways of neovascularization Vasculogenesis Vasculogenesis is the de novo formation of blood vessels. This primarily occurs in the developing embryo with the development of the first primitive ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Femoral Vein
In the human body, the femoral vein is a blood vessel that accompanies the femoral artery in the femoral sheath. It begins at the adductor hiatus (an opening in the adductor magnus muscle) as the continuation of the popliteal vein. It ends at the inferior margin of the inguinal ligament where it becomes the external iliac vein. The femoral vein bears valves which are mostly bicuspid and whose number is variable between individuals and often between left and right leg. Structure Segments *The common femoral vein is the segment of the femoral vein between the branching point of the deep femoral vein and the inferior margin of the inguinal ligament.Page 590 in: *The subsartorial vein or superficial femoral vein are designation ...

Franz Kaspar Hesselbach
Franz Kaspar Hesselbach (27 January 1759 – 24 July 1816) was a German surgeon and anatomist who was a native of Hammelburg. He was a pupil, and later Prosector under Carl Caspar von Siebold (1736–1807) at Würzburg. Later Hesselbach was a lecturer at Würzburg, where one of his students was Konrad Johann Martin Langenbeck (1776–1851). His son, Adam Kaspar Hesselbach (1788–1856) was also a surgeon. As a surgeon, Hesselbach is best known for his work with hernia operations. He was the first to describe a handful of anatomical structures, such as the cribriform fascia (Hesselbach's fascia), interfoveolar ligament (Hesselbach's ligament) and the inguinal triangle (Hesselbach's triangle).
