Cribriform Fascia
The cribriform fascia (also known as the fascia cribrosa, or Hesselbach's fascia) is the portion of the superficial layer of the deep fascia of leg which extends between the sartorius muscle, adductor longus muscle, and inguinal ligament to form the anterior portion of the femoral canal. The cribriform fascia forms numerous openings to allow the passage of vessels and nerves, the most prominent of these being the saphenous opening (saphenous hiatus) (which gives passage to the great saphenous vein). Anatomy Structure An inferior aponeurotic thickening of the cribriform fascia - the falciform margin of sphenous opening - forms the inferior margin of the sapnenous opening, embracing the arch of the great saphenous vein. 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 The great saphenous vein (GSV; ) or long saphenous vein is a large, subcutaneo ...

Deep Fascia Of Leg
The deep fascia of leg or crural fascia forms a complete investment to the muscles, and is fused with the periosteum over the subcutaneous surfaces of the bones. The deep fascia of the leg is continuous above with the fascia lata (deep fascia of the thigh), and is attached around the knee to the patella, the patellar ligament, the tuberosity and condyles of the tibia, and the head of the fibula. Behind, it forms the popliteal fascia, covering in the popliteal fossa; here it is strengthened by transverse fibers, and perforated by the small saphenous vein. It receives an expansion from the tendon of the biceps femoris laterally, and from the tendons of the sartorius, gracilis, semitendinosus, and semimembranosus medially; in front, it blends with the periosteum covering the subcutaneous surface of the tibia, and with that covering the head and malleolus of the fibula; below, it is continuous with the transverse crural and laciniate ligaments. It is thick and dense in the upper a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sartorius Muscle
The sartorius muscle () is the longest muscle in the human body. It is a long, thin, superficial muscle that runs down the length of the thigh in the anterior compartment. Structure The sartorius muscle originates from the anterior superior iliac spine, and part of the notch between the anterior superior iliac spine and anterior inferior iliac spine. It runs obliquely across the upper and anterior part of the thigh in an inferomedial direction. It passes behind the medial condyle of the femur to end in a tendon. This tendon curves anteriorly to join the tendons of the gracilis and semitendinosus muscles in the pes anserinus, where it inserts into the superomedial surface of the tibia. Its upper portion forms the lateral border of the femoral triangle, and the point where it crosses adductor longus marks the apex of the triangle. Deep to sartorius and its fascia is the adductor canal, through which the saphenous nerve, femoral artery and vein, and nerve to vastus medialis pa ...

Adductor Longus Muscle
In the human body, the adductor longus is a skeletal muscle located in the thigh. One of the adductor muscles of the hip, its main function is to adduct the thigh and it is innervated by the obturator nerve. It forms the medial wall of the femoral triangle. Structure The adductor longus arises from the body of pubis inferior to pubic crest and lateral to pubic symphysis. It lies ventrally on the adductor magnus, and near the femur, the adductor brevis is interposed between these two muscles. Distally, the fibers of the adductor longus extend into the adductor canal. It is inserted into the middle third of the medial lip of the '' linea aspera''. Innervation As part of the medial compartment of the thigh, the adductor longus is innervated by the anterior division (sometimes the posterior division) of the obturator nerve. The obturator nerve exits via the anterior rami of the spinal cord The spinal cord is a long, thin, tubular structure made up of nervous tissue ...

Inguinal Ligament
The inguinal ligament (), also known as Poupart's ligament or groin ligament, is a band running from the pubic tubercle to the anterior superior iliac spine. It forms the base of the inguinal canal through which an indirect inguinal hernia may develop. Structure The inguinal ligament runs from the anterior superior iliac crest of the ilium to the pubic tubercle of the pubic bone. It is formed by the external abdominal oblique aponeurosis and is continuous with the fascia lata of the thigh. There is some dispute over the attachments. Structures that pass deep to the inguinal ligament include: * Psoas major, iliacus, pectineus * Femoral nerve, artery, and vein * Lateral cutaneous nerve of thigh *Lymphatics Function The ligament serves to contain soft tissues as they course anteriorly from the trunk to the lower extremity. This structure demarcates the superior border of the femoral triangle. It demarcates the inferior border of the inguinal triangle. The midpoint ...

Femoral Canal
The femoral canal is the medial (and smallest) compartment of the three compartments of the femoral sheath. It is conical in shape. The femoral canal contains lymphatic vessels, and Adipose tissue, adipose and loose connective tissue, as well as - sometimes - a Cloquet's node, deep inguinal lymph node. The function of the femoral canal is to accommodate the distension of the femoral vein when venous return from the leg is increased or temporarily restricted (e.g. during a Valsalva maneuver). The proximal, abdominal end of the femoral canal forms the femoral ring. The femoral canal should not be confused with the nearby adductor canal. Anatomy The femoral canal is bordered: * anterosuperiorly by the inguinal ligament * posteriorly by the pectineal ligament lying anterior to the superior pubic ramus * Medially by the lacunar ligament * Laterally by the femoral vein Physiological significance The position of the femoral canal medially to the femoral vein is of physiologic importa ...

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 stru ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Great Saphenous Vein
The great saphenous vein (GSV; ) or long saphenous vein is a large, subcutaneous, superficial vein of the human leg, leg. It is the longest vein in the body, running along the length of the lower limb, returning blood from the foot, human leg, 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 Toe#Hallux, 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 Palpation, palpated), it runs up the medial (anatomy), 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 re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 the vein that accompanies the femoral artery in the femoral sheath. It is a deep vein that begins at the adductor hiatus (an opening in the adductor magnus muscle) as the continuation of the popliteal vein. The great saphenous vein (a superficial vein), and the deep femoral vein drain into the femoral vein in the femoral triangle when it becomes known as the common femoral vein. It ends at the inferior margin of the inguinal ligament where it becomes the external iliac vein. Its major tributaries are the deep femoral vein, and the great saphenous vein. The femoral vein contains valves. Structure The femoral vein bears valves which are mostly bicuspid and whose number is variable between individuals and often between left and right leg. Course The femoral vein continues into the thigh as the continuation from the popliteal vein at the back of the knee. It drains blood from the deep thigh muscles and thigh bone. Proximal to th ...

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).
