 Good day ladies and gentlemen. My name is Dr. Sanjay Sanyal, professor and department chair of anatomical sciences Finally before we conclude I need to tell you about the cubital fossa itself If we feel here This is the medial epicondyle and if you put my finger here deep inside This is the lateral epicondyle if we were to join them with an imaginary line This is the upper margin of the cubital fossa The infromedial boundary of the cubital fossa is this muscle here. This is the pronator teres muscle How do we know that this is the pronator teres muscle because we know that the median nerve After it exits the cubital fossa. This is the median nerve It goes through the pronator between the two heads of the pronator teres muscle But more of that will be described later The infrolateral boundary of the cubital fossa is formed by the this muscle here This is the bricure radialis muscle which takes origin from the common extensor origin So these are the boundaries of the cubital fossa What about the floor of the cubital fossa the floor of the cubital fossa is formed by upper part is formed by the This this is the bricurellis and the lower part of the floor, which you cannot see here is formed by the supinator muscle What about the roof of the cubital fossa roof had to be removed to show the contents But part of the roof has been preserved and this was the cubital fascia Which has been reinforced by the bicepital aponeurosis and we can see the fibers running in a transverse direction These are actually the fibers which came from the bicep's tendon and this is the remnant of the biceps aponeurosis So what about the contents of the cubital fossa the most important contents are as I have mentioned in the class TAN This is the tendon bicep's tendon This is the artery as break a break a large tree a and this is the median nerve TAN Additionally, we also have the radial nerve Normally the radial nerve is hidden deep inside the brachioradialis. It is anterior to the lateral epicondyle But we have retracted the brachial the brachioradialis to show a part of the radial nerve here And to bring you up to speed this was the beginning of the radial nerve here in the axilla Which went through the radial groove and it supplied all the muscles in the posterior compartment and here It became in front of and now it will continue down into the forearm. So this is the part of the Radial nerve here. So these are the contents of the cubital fossa So this is all for now for today's resection.
