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 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 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 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]
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 patellar network (circulatory anastomosis around the knee-joint, patellar anastomosis, genicular anastomosis, articular vascular network of knee [1] or rete articulare genus [2]) 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.
Its proximal and distal arterial supply consists of perforating branches of the anterior tibial artery and fibular artery. [3] Additional images. Animation. ...
