 Let everybody come because I'm going to the section of the superficial section of the neck. I've decided out the right side. By the way, my name is Dr. Sanjay Sanyal and I'm here with me all the MD1 students and they're all key enthusiastic anatomy students. Okay, so and the camera person is Mr. Doug McLaren and I've got a whole lot of assistants here with me so I can't take all of their names but trust me they're all good ones. They're all better than me. Okay, so this is the section of the right. Just a quick digression at this juncture. Here's a quick snapshot of some of my students. All of them grinning from year to year. So let's take a quick look at what we can see in the structure here. This is the sternocleidomastoid on the right side which has been cut open, which has been cut at the lower portion and reflected. Under the sternocleidomastoid we can see this muscle here. This is the superior belly of the omohide. The right side. Superior belly of the omohide. The inferior belly of the omohide as you know it is attached to the intermediate tendon is attached to the clavicle and the superior belly goes here and gets attached to the higher bone. This bone that you see here, this is the hyoid bone and so we can see that the superior belly, this is the hyoid bone. This is the one which is moving here and this is the one which is giving attachment to the superior belly. Below the hyoid bone this is the thyroid cartilage and we can see the superior thyroid notch here and this is the laryngeal prominence which gives the so-called Adam's apple in males. All of these were covered by the pre-tracheal fascia which has been dissected out. From this thyroid cartilage, hyoid bone, we have another muscle which is going up and this muscle that you see here, this is the geniohyoid muscle, the geniohyoid muscle and you can see it is extending from the hyoid bone to the genial tubercle on the inner surface of the mandible near the symphysis mentai. So this is one side geniohyoid and since this is the hyoid bone this is the other side geniohyoid and in between the two geniohyoid we can see this muscle here. This is the mylohyoid which forms the floor of the mouth. Let's continue just lateral to the geniohyoid we can see another muscle here. This is the anterior belly of the digastric. Antibial of the digastric, we can see the intermediate tendon of the digastric and we can see the posterior belly of digastric going behind. The intermediate tendon is it has a visual sling to the greater corneum of hyoid bone. So this is the digastric triangle that we see here, the anterior belly of digastric, the posterior belly of digastric and the mandible. And in the digastric triangle we can see the submandible salivary gland and we can see the submandible lymph nodes here. So this is the digastric triangle. Putting the sternocleidomastoid in place we can see that the space between the upper half of the sternocleidomastoid and the omohyoid and the posterior belly of digastric this is the carotid triangle. So when I take this further deeper inside here we shall see the bifurcation of the common carotid and the internal jugular vein. Okay, let's continue. This is the thyroid cartilage. So we can see the cut portion of the muscle here, one small slip of muscle here. This is the sternohyoid muscle. The sternohyoid muscle, the lower portion has been cut out. It extends on the manabrium sterni from the inner surface of the manabrium sterni and goes all the way to the hyoid bone. And under that we can see this muscle here which is attached to the oblique line of the thyroid cartilage and this is the sternothyroid muscle. And about this deep to this will be the thyroid hyoid muscle. When we dissect out all these muscles and we reflect them then we can see the structure which I shall dissect more in detail and show you later on which is going to be our last class and that is this gland. This is the right lobe of the thyroid gland. This is the right lobe of the thyroid gland. Similarly the left lobe of the thyroid gland will be here and the isthmus will be in front of the second, third and fourth tracheal rings. So just to give you a quick overview recap of the cartilages, this is the hyoid bone. This is the thyroid cartilage and under this this projection that we see here, this is the cricoid and below that is the tracheal rings. This between the two anterior belly of digastric and the hyoid bone. This is the submental triangle. The floor of the submental triangle is formed by the mylohyde and this contents of this are the submental lymph nodes, the submental vein and the submental artery. So we have seen the submental triangle, we have seen the digastric triangle, we have seen the carotid triangle and finally the triangle between the lower half of the anterior border of the sternocleidomastoid, the supine belly of the omohyd and the midline of the neck. This is the muscular triangle or the omotric triangle where one of the main contents is the thyroid leg. So these are the structures which I wanted to show you in the anterior dissection of the neck on the right side. If there are any questions or comments, please put them in the comment section below. Thank you ladies and gentlemen, have a nice day. Dr. Sanjay Sanyal signing out. Thank you very much.
