The inferior genicular arteries (inferior articular arteries), two in number, arise from the popliteal beneath the gastrocnemius. On the inside of the knee, is the medial inferior genicular artery, and on the outer side is the lateral inferior genicular 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 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.
The popliteal artery is a deeply placed continuation of the femoral artery opening in the distal portion of the adductor magnus muscle. It courses through the popliteal fossa and ends at the lower border of the popliteus muscle, where it branches into the anterior and posterior tibial arteries.
The common fibular 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.
The superior genicular arteries, two in number, arise one on either side of the popliteal artery, and wind around the femur immediately above its condyles to the front of the knee-joint. The medial superior genicular artery is on the inside of the knee and the lateral superior genicular artery is on the outside.
The lateral superior genicular artery is a branch of the popliteal artery that supplies a portion of the knee joint.
The medial superior genicular artery is a branch of the popliteal artery. It runs deep to the semimembranosus, semitendinosus, and tendon of the adductor magnus, and superior to the medial head of the gastrocnemius.
The lateral inferior genicular is an artery of the leg.
The medial inferior genicular is an artery of the leg.
The lateral circumflex femoral artery is an artery in the upper thigh. It is usually a branch of the profunda femoris artery, and produces three branches. It is mostly distributed to the muscles of the lateral thigh, supplying arterial blood to muscles of the knee extensor group.
The cruciate anastomosis is a circulatory anastomosis in the upper thigh formed by the inferior gluteal artery, the lateral and medial circumflex femoral arteries, the first perforating artery of the deep femoral artery, and the anastomotic branch of the posterior branch of the obturator 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.
In anatomy, arterial tree is used to refer to all arteries and/or the branching pattern of the arteries. This article regards the human arterial tree. Starting from the aorta:
The posterior tibial recurrent artery, an inconstant branch, is given off from the anterior tibial before that vessel passes through the gap between superior tibio-fibular joint and upper border of interosseous membrane.
The descending genicular artery arises from the femoral artery just before its passage through the adductor hiatus.
The sural arteries are two large branches, lateral and medial, which are distributed to the gastrocnemius, soleus, and plantaris muscles. Sural means related to the calf. The term applies to any of four or five arteries arising from the popliteal artery, with distribution to the muscles and integument of the calf, and with anastomoses to the posterior tibial, medial and lateral inferior genicular arteries.
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 (3.1–5.3 in) superior to the adductor tubercle.
The patellar network is an intricate network of blood vessels around and above the patella, and on the contiguous ends of the femur and tibia, forming a superficial and a deep plexus.
The genicular arteries are six arteries in the human leg, five of which are branches of the popliteal artery, that anastomose in the knee region in the patellar network or genicular anastomosis. They supply blood to the patella, together with contributions from the descending genicular artery, anterior tibial recurrent artery, and descending branch of lateral circumflex femoral artery.
