Pes Anserinus (leg)
Pes anserinus ("goose foot") refers to the conjoined tendons of three muscles of the thigh. It inserts onto the anteromedial (front and inside) surface of the proximal tibia. The muscles are the sartorius, gracilis and semitendinosus sometimes referred to as the guy ropes. The name "goose foot" arises from the three-pronged manner in which the conjoined tendon inserts onto the tibia. Structure The three tendons, from front to back, that conjoin to form the pes anserinus come from the sartorius muscle, the gracilis muscle, and the semitendinosus muscle. It inserts onto the proximal anteromedial surface of the tibia. The pes anserinus is around 5 cm below the medial tibial joint line. It lies superficial to the tibial insertion of the medial collateral ligament of the knee. Clinical significance Pes anserinus tendinitis/bursitis syndrome, or pes anserine bursitis, is a cause of Knee pain, chronic knee pain and weakness. - "Pes anserinus bursitis" It occurs when the medial por ...

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 of thigh, 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 muscle, gracilis and semitendinosus muscles in the pes anserinus (leg), 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 muscle, adductor longus marks the apex of the triangle. Deep to sartorius and its fascia is the adductor canal, throu ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Guy Ropes
A guy-wire, guy-line, guy-rope, or stay, also called simply a guy, is a tensioned cable designed to add stability to a free-standing structure. They are used commonly for ship masts, radio masts, wind turbines, utility poles, and tents. A thin vertical mast supported by guy wires is called a guyed mast. Structures that support antennas are frequently of a lattice construction and are called "towers". One end of the guy is attached to the structure, and the other is anchored to the ground at some distance from the mast or tower base. The tension in the diagonal guy-wire, combined with the compression and buckling strength of the structure, allows the structure to withstand lateral loads such as wind or the weight of cantilevered structures. They are installed radially, usually at equal angles about the structure, in trios and quads. As the tower leans a bit due to the wind force, the increased guy tension is resolved into a compression force in the tower or mast and a late ...

Inflammation
Inflammation (from la, wikt:en:inflammatio#Latin, inflammatio) is part of the complex biological response of body tissues to harmful stimuli, such as pathogens, damaged cells, or Irritation, irritants, and is a protective response involving immune cells, blood vessels, and molecular mediators. The function of inflammation is to eliminate the initial cause of cell injury, clear out necrotic cells and tissues damaged from the original insult and the inflammatory process, and initiate tissue repair. The five cardinal signs are heat, pain, redness, swelling, and Functio laesa, loss of function (Latin ''calor'', ''dolor'', ''rubor'', ''tumor'', and ''functio laesa''). Inflammation is a generic response, and therefore it is considered as a mechanism of innate immune system, innate immunity, as compared to adaptive immune system, adaptive immunity, which is specific for each pathogen. Too little inflammation could lead to progressive tissue destruction by the harmful stimulus (e.g. b ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Knee Pain
Knee pain is pain in or around the knee. The knee joint consists of an articulation between four bones: the femur, tibia, fibula and patella. There are four compartments to the knee. These are the medial and lateral tibiofemoral compartments, the patellofemoral compartment and the superior tibiofibular joint. The components of each of these compartments can experience repetitive strain, injury or disease. Running long distance can cause pain to the knee joint, as it is a high-impact exercise. Causes Injuries Some common injuries based on the location include: *Sprain (Ligament sprain) **Medial collateral ligament ** Lateral collateral ligament **Anterior cruciate ligament **Posterior cruciate ligament *Tear of meniscus ** Medial meniscus **Lateral meniscus *Strain (Muscle strain) **Quadriceps muscles **Hamstring muscles ** Popliteal muscle **Patellar tendon **Hamstring tendon **Popliteal tendon *Hemarthrosis – Hemarthrosis tends to develop over a relatively short period afte ...

Pes Anserine Bursitis
Pes anserine bursitis is an inflammatory condition of the medial (inner) knee at the anserine bursa, a sub muscular bursa, just below the pes anserinus. Pathology The pes anserinus is where the tendons of the sartorius, gracilis, and semitendinosus join at the medial knee, into the anteromedial proximal tibia. Pes anserine bursitis may result from stress, overuse, obesity and trauma to this area. An occurrence of pes anserine bursitis commonly is characterized by pain at the medial knee and upper tibial region, especially when climbing stairs, tenderness, and local swelling. Pathophysiology The etymology of the name relates to the insertion of the conjoined tendons into the anteromedial proximal tibia. From anterior to posterior, the pes anserinus is made up of the tendons of the sartorius, gracilis, and semitendinosus muscles. The tendon's name, which literally means "goose's foot," was inspired by the pes anserinus's webbed, footlike structure. The conjoined tendon lies s ...

Medial Collateral Ligament
The medial collateral ligament (MCL), or tibial collateral ligament (TCL), is one of the four major ligaments of the knee. It is on the medial (inner) side of the knee joint in humans and other primates. Its primary function is to resist outward turning forces on the knee. Structure It is a broad, flat, membranous band, situated slightly posterior on the medial side of the knee joint. It is attached proximally to the medial epicondyle of the femur immediately below the adductor tubercle; below to the medial condyle of the tibia and medial surface of its body. It resists forces that would push the knee medially, which would otherwise produce valgus deformity. The fibers of the posterior part of the ligament are short and incline backward as they descend; they are inserted into the tibia above the groove for the semimembranosus muscle. The anterior part of the ligament is a flattened band, about 10 centimeters long, which inclines forward as it descends. It is inserted into ...

Tibia
The tibia (; ), also known as the shinbone or shankbone, is the larger, stronger, and anterior (frontal) of the two bones in the leg below the knee in vertebrates (the other being the fibula, behind and to the outside of the tibia); it connects the knee with the ankle. The tibia is found on the medial side of the leg next to the fibula and closer to the median plane. The tibia is connected to the fibula by the interosseous membrane of leg, forming a type of fibrous joint called a syndesmosis with very little movement. The tibia is named for the flute ''tibia''. It is the second largest bone in the human body, after the femur. The leg bones are the strongest long bones as they support the rest of the body. Structure In human anatomy, the tibia is the second largest bone next to the femur. As in other vertebrates the tibia is one of two bones in the lower leg, the other being the fibula, and is a component of the knee and ankle joints. The ossification or formation of the bone ...

Semitendinosus Muscle
The semitendinosus () is a long superficial muscle in the back of the thigh. It is so named because it has a very long tendon of insertion. It lies posteromedially in the thigh, superficial to the semimembranosus. Structure The semitendinosus, remarkable for the great length of its tendon of insertion, is situated at the posterior and medial aspect of the thigh. It arises from the lower and medial impression on the upper part of the tuberosity of the ischium, by a tendon common to it and the long head of the biceps femoris; it also arises from an aponeurosis which connects the adjacent surfaces of the two muscles to the extent of about 7.5 cm. from their origin. The muscle is fusiform and ends a little below the middle of the thigh in a long round tendon which lies along the medial side of the popliteal fossa; it then curves around the medial condyle of the tibia and passes over the medial collateral ligament of the knee-joint, from which it is separated by a bursa, and is ...

Gracilis Muscle
The gracilis muscle (; Latin for "slender") is the most superficial muscle on the medial side of the thigh. It is thin and flattened, broad above, narrow and tapering below. Structure It arises by a thin aponeurosis from the anterior margins of the lower half of the symphysis pubis and the upper half of the pubic arch. The muscle's fibers run vertically downward, ending in a rounded tendon. This tendon passes behind the medial condyle of the femur, curves around the medial condyle of the tibia where it becomes flattened, and inserts into the upper part of the medial surface of the body of the tibia, below the condyle. For this reason, the muscle is a lower limb adductor. At its insertion the tendon is situated immediately above that of the semitendinosus muscle, and its upper edge is overlapped by the tendon of the sartorius muscle, which it joins to form the pes anserinus. The pes anserinus is separated from the medial collateral ligament of the knee-joint by a bursa. A ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |
