Popliteal Artery Scheme (Course, Branches, Patellar Network) | Anatomy — Transcript

Full transcript

1. 0:00Hello and welcome to another video, in this  video we’re gonna be looking at the Popliteal
2. 0:04artery and the patellar network. Now the popliteal artery is a
3. 0:08direct continuation of femoral artery.  So if we now follow the femoral artery
4. 0:13And look from this perspective, behind the knee You’ll see that the artery runs very superficially
5. 0:19through the popliteal fossa to the popliteus  muscle, where it ends by dividing into
6. 0:24Its two terminal branches; these are the  anterior and the posterior tibial arteries.
7. 0:31Along its course, the popliteal artery gives Off 6 side branches for the patellar network
8. 0:37and the superficial muscles for the  posterior group of the lower leg.
9. 0:41The first two are the Superior medial and  the superior lateral genicular arteries,
10. 0:47which winds around the medial and lateral condyles  of the femur, to supply the knee with blood.
11. 0:54And since we have Superior arteries, we’re also  gong to have the Inferior medial and the Inferior
12. 1:00Lateral genicular arteries, which winds around  the Tibia and the Fibula to also supply the knees.
13. 1:06And then there’s the Middle genicular artery.  It pierces the articular capsule, enters the
14. 1:13articular cavity and supplies the ligaments,  meniscs and the synovial folds of the knee.
15. 1:20The last arteries the popliteal artery gives  off, are the Sural arteries, which descends
16. 1:25and supply the triceps surae muscle. Now that  was all for the side branches of the popliteal
17. 1:32artery. Overall, the popliteal artery and  its branches provide an arterial supply to
18. 1:37the knee joint, the leg and foot. Let’s now Go ahead and cover the patellar network,
19. 1:41or the Rete articulare genu in latin. First, The Superior and the Inferior medial and lateral
20. 1:48genicular arteries will anestemose like this. Then there’s the descending genicular artery
21. 1:54coming from the Femoral artery if  you remember this one. It connects
22. 1:58directly to the superior medial genicular artery; And gives off a side branch called the saphenous
23. 2:03branch which provides a collateral blood flow to  the knee. Then remember that the lateral femoral
24. 2:25circumflex artery divides into three branches, the  ascending, transverse and the descending branch?
25. 2:31The descending branch of the lateral  femoral circumflex artery will go down
26. 2:36and contribute to the patellar network on the  lateral side. Then from the inferior side,
27. 2:42The anterior tibial artery will give off  two branches called the anterior recurrent
28. 2:48tibial branch from the anterior side,  and a posterior recurrent tibial branch,
29. 2:55which emerges right before the anterior tibial  artery reaches the anterior side. As you see here
30. 3:02these two arteries will contribute to the  patellar network by anastomosing with the inferior
31. 3:08lateral genicular artery. Then lastly The posterior tibial artery give off the
32. 3:14circumflex fibular branch to also take part in  the patellar network by anastomosing with the
33. 3:19inferior lateral genicular  artery. So that was all I
34. 3:23had for the popliteal artery and the genicular  network, and I hope this was helpful.
