Highest Genicular
The descending genicular artery (highest genicular artery) arises from the femoral artery just before it passes through the adductor hiatus. It immediately divides into two branches: * a saphenous branch, which classically joins with the medial inferior genicular artery. * muscular and articular branches. Structure Saphenous branch The saphenous branch pierces the aponeurotic covering of the adductor canal, and accompanies the saphenous nerve to the medial side of the knee. It passes between the sartorius muscle and the gracilis muscle, and, piercing the fascia lata, is distributed to the integument of the upper and medial part of the leg, anastomosing with the medial inferior genicular artery. Articular branches The articular branches descend within the vastus medialis muscle, and in front of the tendon of the adductor magnus muscle, to the medial side of the knee, where they join with the medial superior genicular and anterior recurrent tibial artery. A branch from this v ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Femoral Artery
The femoral artery is a large artery in the thigh and the main arterial supply to the thigh and leg. The femoral artery gives off the deep femoral artery or profunda femoris artery and descends along the anteromedial part of the thigh in the femoral triangle. It enters and passes through the adductor canal, and becomes the popliteal artery as it passes through the adductor hiatus in the adductor magnus near the junction of the middle and distal thirds of the thigh. Structure The femoral artery enters the thigh from behind the inguinal ligament as the continuation of the external iliac artery. Here, it lies midway between the anterior superior iliac spine and the symphysis pubis (Mid-inguinal point). Segments In clinical parlance, the femoral artery has the following segments: *The common femoral artery (CFA) is the segment of the femoral artery between the inferior margin of the inguinal ligament and the branching point of the deep femoral artery/profunda femoris artery.

Vastus Medialis Muscle
The vastus medialis (vastus internus or teardrop muscle) is an extensor muscle located medially in the thigh that extends the knee. The vastus medialis is part of the quadriceps muscle group. Structure The vastus medialis is a muscle present in the anterior compartment of thigh, and is one of the four muscles that make up the quadriceps muscle. The others are the vastus lateralis, vastus intermedius and rectus femoris. It is the most medial of the "vastus" group of muscles. The vastus medialis arises medially along the entire length of the femur, and attaches with the other muscles of the quadriceps in the quadriceps tendon. The vastus medialis muscle originates from a continuous line of attachment on the femur, which begins on the front and middle side (anteromedially) on the intertrochanteric line of the femur. It continues down and back (posteroinferiorly) along the pectineal line and then descends along the inner (medial) lip of the linea aspera and onto the medi ...

Lateral Superior Genicular Artery
The lateral superior genicular artery is a branch of the popliteal artery that supplies a portion of the knee joint. Course It passes above the lateral condyle of the femur, beneath the tendon of the Biceps femoris. Branching It divides into a superficial and a deep branch; the superficial branch supplies the vastus lateralis, and anastomoses with the descending branch of the lateral femoral circumflex and the lateral inferior genicular arteries; the deep branch supplies the lower part of the femur and knee-joint, and forms an anastomotic arch across the front of the bone with the highest genicular and the medial inferior genicular arteries.

Femur
The femur (; ), or thigh bone, is the proximal bone of the hindlimb in tetrapod vertebrates. 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 (shinbone) and patella (kneecap), forming the knee joint. By most measures the two (left and right) femurs are the strongest bones of the body, and in humans, the largest and thickest. Structure The femur is the only bone in the upper leg. The two femurs converge medially toward the knees, where they articulate with the proximal ends of the tibiae. The angle of convergence of the femora is a major factor in determining the femoral-tibial angle. Human females have thicker pelvic bones, causing their femora to converge more than in males. In the condition ''genu valgum'' (knock knee) the femurs converge so much that the knees touch one another. The opposite extreme is ''genu varum'' (bow-leggedness). In the general populatio ...

Patellar Surface Of Femur
The intercondylar fossa of femur (intercondyloid fossa of femur, intercondylar notch of femur) is a deep notch between the rear surfaces of the medial Medial may refer to: Mathematics * Medial magma, a mathematical identity in algebra Geometry * Medial axis, in geometry the set of all points having more than one closest point on an object's boundary * Medial graph, another graph that re ... and lateral epicondyle of the femur, two protrusions on the distal end of the femur (thigh bone) that joins the knee. On the front of the femur, the condyles are but much less prominent and are separated from one another by a smooth shallow articular depression called the patellar surface because it articulates with the posterior surface of the patella (kneecap). The intercondylar fossa of femur and/or the patellar surface may also be referred to as the patellar groove, patellar sulcus, patellofemoral groove, femoropatellar groove, femoral groove, femoral sulcus, trochlear groove o ...

Anterior Recurrent Tibial Artery
The anterior tibial recurrent artery is a small artery in the leg. It arises from the anterior tibial artery, as soon as that vessel has passed through the interosseous space. It ascends in the tibialis anterior muscle, ramifies on the front and sides of the knee-joint, and assists in the formation of the patellar plexus by anastomosing with the genicular branches of the popliteal, and with the highest genicular artery.

Medial Superior Genicular Artery
The medial superior genicular, a branch of the popliteal artery, runs in front of the Semimembranosus and Semitendinosus, above the medial head of the Gastrocnemius, and passes beneath the tendon of the Adductor magnus. It divides into two branches, one of which supplies the vastus medialis, anastomosing with the highest genicular and medial inferior genicular arteries; the other ramifies close to the surface of the femur, supplying it and the knee-joint, and anastomosing with the lateral superior genicular artery. The medial superior genicular artery is frequently of small size, a condition, which is associated with an increase in the size of the highest genicular.

Medial Inferior Genicular Artery
The medial inferior genicular is an artery of the leg. Course It first descends along the upper margin of the popliteus, to which it gives branches; it then passes below the medial condyle of the tibia, beneath the tibial collateral ligament, at the anterior border of which it ascends to the front and medial side of the joint, to supply the upper end of the tibia and the knee-joint, anastomosing with the lateral inferior and medial superior genicular arteries.

Adductor Hiatus
In human anatomy, the adductor hiatus also known as hiatus magnus is a hiatus (gap) between the adductor magnus muscle and the femur that allows the passage of the femoral vessels from the anterior thigh to the posterior thigh and then the popliteal fossa. It is the termination of the adductor canal and lies about 8–13.5 cm. superior to the adductor tubercle. Structure Kale et al. classified the adductor hiatus according to its shape and the structures surrounding. An adductor hiatus is described as oval or bridging depending on the shape of the upper boundary. It can also be described as muscular or fibrous depending on whether the structure surrounding is the muscular part or the tendinous part of the adductor magnus muscle. For example, the top drawing on the right shows an oval fibrous type of adductor hiatus, and the bottom one shows a bridging muscular adductor hiatus. Four structures are associated with the adductor hiatus. However, only two structures enter and the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fascia Lata
The fascia lata is the deep fascia of the thigh. It encloses the thigh muscles and forms the outer limit of the fascial compartments of thigh, which are internally separated by the medial intermuscular septum and the lateral intermuscular septum. The fascia lata is thickened at its lateral side where it forms the iliotibial tract, a structure that runs to the tibia and serves as a site of muscle attachment. Structure The fascia lata is an investment for the whole of the thigh, but varies in thickness in different parts. It is thicker in the upper and lateral part of the thigh, where it receives a fibrous expansion from the gluteus maximus, and where the tensor fasciae latae is inserted between its layers; it is very thin behind and at the upper and medial part, where it covers the adductor muscles, and again becomes stronger around the knee, receiving fibrous expansions from the tendon of the biceps femoris laterally, from the sartorius medially, and from the quadriceps femoris ...

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] |
