The anterior tibial artery is a branch of the popliteal artery. [1] It originates at the distal end of the popliteus muscle posterior to the tibia. The artery typically passes anterior to the popliteus muscle prior to passing between the tibia and fibula through an oval opening at the superior aspect of the interosseus membrane.
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 middle genicular artery is a small branch of the popliteal artery that originates inferior or distal to both the superior genicular arteries as well as the sural arteries. Inferior or distal to the origins of the superior and middle genicular arteries are the two inferior genicular arteries: Medial inferior genicular artery
The circumflex fibular artery (circumflex fibular branch, circumflex branch of posterior tibial artery, or circumflex peroneal branch of posterior tibial artery) is a branch of the posterior tibial artery which supplies blood to the knee. [1] The artery branch of the anterior tibial artery, at its initial (or superior) segment, winds around the ...
The lower leg is divided into four compartments by the interosseous membrane of the leg, the anterior intermuscular septum, the transverse intermuscular septum and the posterior intermuscular septum. [1] Each compartment contains connective tissue, nerves and blood vessels.
The popliteal vein is formed by the junction of the venae comitantes of the anterior tibial vein and the posterior tibial vein at the lower border of the popliteus muscle. It travels on the medial side of the popliteal artery. [1] It is superficial to the popliteal artery. [2]
It supplies a perforating branch to both the lateral and anterior compartments of the leg; it also provides a nutrient artery to the fibula. Some sources claim that the fibular artery arises directly from the posterior tibial artery, but vascular and plastic surgeons note the clinical significance of the tibial-fibular trunk. [2]
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 ...
