So if I rotate the model around you can see the lateral inferior genicular coming off the popliteal artery, and you can also see this other branch anastomosing, which is the circumflex fibular artery of the posterior tibial artery, which I'll come back to talk about. I've just switched over to a different model, which illustrate how the anterior tibial recurrent artery anastomoses with the lateral inferior genicular branch of the popliteal. The anterior tibial recurrent artery you can see here. The posterior tibial recurrent artery is not always present and its not shown on this model.
The branches of the anterior tibial artery include the posterior tibial recurrent, and the anterior tibial recurrent arteries proximally. And rotating the model around you can see how it enters into the anterior, or extensor compartment of the leg, just above the interosseus membrane. So you can see it here in this model in purple, and it arises just below the inferior border of the popliteus muscle. Now to begin with let's take a look at the branches of the anterior tibial artery. So this tibiofibular trunk gives off the fibular artery and the posterior tibial artery. Now the bit between the origin of the anterior tibial and the origin of the fibular artery, is sometimes referred to as the tibioperoneal trunk, or the tibioperoneal trunk. So the posterior tibial artery gives off the peroneal, or fibular artery, which you can see here. And if I rotate the model around slightly, you can see the anterior tibial artery in purple.
You've got the posterior tibial artery, which you can see here in red. What we're looking at here is a posterior view of the knee and the leg, and we can see the popliteal artery running behind the knee joint and it gives off two branches. So this tutorial follows on from the one I did on the arterial supply to the knee. Hi this is Peter from AnatomyZone and in this tutorial we're going to take a look at the arterial supply to the leg.
