 Good day ladies and gentlemen, Dr. Sanjay Sanyal, department chair professor of anatomical sciences. Welcome to our next dissection. Let's take a look at this dissected specimen here. Let's look at the lateral side of the forearm. We can see a vein running very superficially. This vein that you see here. Everybody has it. You can see it on your own self also. This is the cephalic vein. And I'll tell you how it starts in a later dissection. So this is the cephalic vein. Now this vein has got a lot of anatomical variations. So here we are seeing one typical situation but there can be many variations. The cephalic vein then continues and it continues on the lateral side of the, on the roof of the cubital fossa. And it continues on the lateral aspect of the biceps brachii. And then it runs in the dentorectal groove. And it goes and pierces the costochloroquine membrane which I mentioned in earlier dissection. And it opens into the axillary vein. But let's continue with our story. This cephalic vein, it's a superficial vein. It's present in the superficial fascia. It gives a communication on the roof of the cubital fossa. And this communication you can see very clearly here. This is the communication. This is known as the median cubital vein. And in fact, nurses use this vein to draw blood from your elbow. Next time you give a blood sample, she will be poking here most probably. Okay. So this is the median cubital vein. This is also present in the roof of the cubital fossa. And it bridges across the roof of the cubital fossa. And it communicates with this vein that you see here. This is the basillic vein. The basillic vein is also a prominent superficial vein which runs on the medial side of the arm. And this basillic vein, and in my earlier dissection I had mentioned, this basillic vein is accompanied by this nerve which is referred to as the medial cutaneous nerve of the forearm. But anyway, let's continue. The basillic vein then continues up. And it unites with the vinaicometantes of the axillary artery which I'm going to mention just now. And it forms what is known as the brachial vein. And you can see the brachial vein here. Because the vein is very thin walled and it had collapsed, I have put a probe inside. The brachial vein then continues up. And at the lower border of the teres major, the brachial vein becomes the axillary vein. And you can see the probe has gone into the axillary vein. And the axillary vein then goes through the cervical axillary canal and it opens into the subclavian vein. Part of it is visible from our previous dissection. This is the other end of the subclavian vein. So that is about the basillic vein, the axillary vein, continuing as the axillary vein. Now let's go in the reverse direction and let's talk about the axillary artery. These are two cut ends. As I mentioned in my earlier dissection, this is the subclavian artery, which emerges through the scalyne triangle between the scalyneus anterior and the scalyneus medius muscle. So this is the cut end of the subclavian artery. At the outer border of the first ring, the subclavian artery becomes known as the axillary artery. And the axillary artery also has got three parts, which is divided by the pectoralis minor. The portion from the outer border of the first ring to the pectoralis minor is the first part. The portion behind the pectoralis minor is the second part. And the portion from the pectoralis minor to the lower border of the teres major is the third part. So this is the axillary artery. And we can trace the axillary artery all the way down the middle side of the arm, lateral to the axillary vein, and it continues on the middle side of the arm, accompanied by the median nerve, which is this is the median nerve which I had shown you earlier, and this continues into the, and you can see this is the brachial vein now, the artery now. And it goes into the cubital fossa, accompanied by the median nerve. The relationship in the brachial, in the cubital fossa is the biceps tendon is lateral, then the brachial artery, and then the median nerve. Tendon artery nerve, T-A-N. Thank you very much for watching, ladies and gentlemen. Have a nice day.
