 Good day everybody. Dr. Sanger Sanyal, welcome to the next dissection demonstration. This time I'm going to mention the neurovascular structures on the flexor aspect of the forearm. So let's start off from the cubital fossa. We see this is the median nerve. The median nerve goes through two muscles and you can see it is going through the two heads of the pronator theories, the humeral head and the ulnar head and you can clearly see it is going through and this is the place where the median nerve can get entrapped in the condition known as the pronator syndrome. After it has passed through the pronator theories it again goes through yet another muscle and what is that muscle? You can see it here. It goes through the flexor digitorum superficialis muscle which I have split open. The flexor digitorum superficialis also has two heads, a humeral ulnar head and a radial head and you can see this is the radial head. This is the radial head and this is the humeral ulnar head and you can see the median nerve is passing through the humeral ulnar and the radial heads. So this is the second muscle it pierces through and then it runs undercover of the flexor digitorum superficialis all along here and it comes to the wrist between the flexor carbide radialis and the palmaris longus and it enters the carpal tunnel and my forceps has gone inside. This is the carpal tunnel and it passes through the carpal tunnel which I'm going to mention in my subsequent video and then it reaches the palm. So this is the course of the median nerve and this is an important site where we can give anesthesia to anesthetize the median nerve and this is the site where the median nerve can get compressed in the condition known as carpal tunnel syndrome. So that is about the median nerve. Now let's take the next neurovascular structure. Again let's start from the cubital fossa. This is the brachial artery and we can see the brachial artery is dividing into two major branches in the cubital fossa. One is this branch, the other is this branch. This is the ulnar branch and this is the radial branch. The ulnar branch gives rise to the introsius recurrent. It gives rise to the introsius artery which divides into an anterior and posterior introsius artery. We cannot see that here but then after that the ulnar artery continues undercover of the flexor carbide ulnaris and we can see it coming here. This is the ulnar artery. The ulnar artery is situated lateral to the ulnar nerve and they are both undercover of the flexor carbide ulnaris. The ulnar artery does not go through the carpal tunnel. It goes superficial to the carpal tunnel and it gives rise to a dorsal carpal branch and then it forms the superficial palmar arch on the palm. So this is about the ulnar artery. Now let's take the course of the other division. The ulnar artery also gives anterior and posterior ulnar recurrent arteries which participate in the elbow anastomosis. Now let's take the other branch that is the radial branch. This is the radial artery. The radial artery does not have too many branches. It has just one recurrent branch which participates in the elbow anastomosis called the radial recurrent. Otherwise it does not have any branch in the forearm. It runs mostly under cover of the brachioradialis and you can see it running under cover of the brachioradialis and this is the radial artery and it runs down and we can feel the pulsation of the radial artery lateral to the flexor carpal radialis tendon. This is the place where we feel the pulsation the so-called radial pulse. This radial artery then does something very interesting which I'm going to show you in another video in more detail but we see that it goes deep to these tendons and they come to this region which is called the anatomical snuff box and after that the rest of the course I will mention in yet another video. So this is the course of the radial artery. So thank you very much for watching ladies and gentlemen. These are the neurovascular structures in the flexor aspect of the hand.
