 Hello, everybody. Andrea here with Dental L. Let's talk about what you have to know about lymphatic drainage of the head and neck. You're probably thinking, what the heck is that? We know the lymph nodes are so important for fighting off disease and helping to remove toxins, but you do need to know a little bit more of that. I have some great photos for you. I am always about visual learning, study this, memorize this, print it out. It's a great thing to know because when you're doing the external oral cancer screening, you should be checking these things on your clients. I tell my clients it's like they're getting their own personal facial massage because that's what you're doing. You're not going to tickle them like this. You need to be feeling for those lymph nodes. If there's anything swollen, that's what you do in the oral cancer screening for the external part of it. You have the superficial vessels and the deep vessels, so you do have to know the different types. More specific for the deep ones, you need to know that you have the left trunk and the right trunk. Looking at this again, you kind of see the different trunks, but then you have nodes. All of those nodes, so lymph nodes, are what you're feeling, the nodes. The superficial nodes are not the deep ones. You have the superficial, then you have the deep ones. There's many different superficial nodes. I list them all here for you, but then you should also go back at the image here, and then you can see them here to really help you visualize where they are. Continue. There's lots of superficial nodes. I have another photo for you just to remind you, but it's not as busy as this one, just to show you guys something in a different way. You have the deep ones. There's many different deep ones. They're harder to pronounce if you ask me. Oh, I just realized, oh no, sorry, I thought I had two of them twice, but no, they're slightly different. I talk about the deep ones as well. The deep ones are basically the ones that have to do with the head and neck. Those are the lymph nodes having to do with the head and neck, whereas the superficial ones are different, and we talk about that. I keep it simple here where I've put it all into like a list format for you. And then we talk about as well, the tonsiler ring. Your tonsils have lymph nodes in them, extremely important. You need to know about the tonsils and the different types. So I talk about that as well because it's all related to the lymph nodes and removing toxins. So this is just a quick overview. I teach you more inside the course, inside our live classes for the Board Exam Prep Academy. Let me know you guys if you have any questions, and I'll see you guys in the next video.
