Okay, we get to talk about the anatomy of the nose, you know, the nose sits right in front of the face, you can't ignore it and it connects the features on the face, all of them connects the forehead connects the eyes, it's connected to the cheeks and the mouth. So it's pretty important and we have to get our, our hands and our arms around it to draw decent one. So let's look at what are the main features of the nose. So basically, it's got bones, cartilage, and some fatty tissue. So it's got the nasal bones here. There's the triangular portions of the cartilage and the wing of the nose, which is called the Allah.

Okay. Those are cartilage. Now, the bone part, some of that anatomy here. That we need to know is this area here, it's the Keystone. We call it the glove Bella. That's the anatomical name for it the club l that's important.

Right and you can see how it connects the eyes to the nose and the forehead to the eyes into the nose so that the elbow is pretty important. Then we've got the nasal bone here, right, all this stuff here and you can see where it cuts off right there. And all this stuff here is cartilage. Okay, so we'll get into that but we've got the nasal bone coming out, extending out from the glabella. And then we've got these cartilage processes. So the lateral process Have cartilage.

So lateral just means on the side, right? And you can see there, these kind of triangular pieces to it. And we've got the all our cartilage here. Right? So you can think of these as certain kinds of shapes and connected to that. Right here.

This next little piece, that's the fatty part of the wing of the nose. Right, so that's the wing of the nose right here, right here. So it's part cartilage, and in part, fatty. So this is the ball of the nose. Right here. If we're looking underneath is the septum, right?

So that's separating the two nostrils and you can see that the nose itself, the nose holes are like little kind of like little kidney bean shapes, right? They kind of come in like this. The way we see him a lot of times is a bump here. Depending on the lighting, there like they can be like a little comma. Okay, or you might see it more heavily shaded on the bottom part than the top. Here.

It's heavily shaded on the top. So it's thicker here. This one it's more heavily shaded on the bottom. Okay, so it all depends on the light, but then little commas. You can think of him like that. This part right here where the nasal bone connects to?

Well, it's the side of the nose. And this is the hardest part. So we're going to explore this, but it goes into this area here, which is the maxilla. Right? And then you have this bump. And that's part of the lower part of the orbicularis Oculus.

So that's where the eye socket is. You can see there's this, this kind of bump here. And then it connects to the side of the nose here. So let's explore that because that's oftentimes doesn't jump out at you. It's not real clear. And so let's explore that.

Here's how it looks on a regular face, right? You've got these cartilaginous parts here on the lateral side. And you have the septum also cartilaginous in the middle, separating the two lateral parts of the upper cartilage. So that's called the septum. Right? And then it also divides this lower all our cartilage cartilage.

Right. And so on the bottom of the nose. A lot of times you get this kind of division or bifurcation. And, you know, a lot of Europeans have this mostly Asians don't have it so much. And then here you've got the fatty part of the wing of the nose. Let's do that.

Read. So that's the fatty part. Then here you've got the septum here, and then the fatty part on the right side. Okay, here's the nasal bone right and you can see it's divided right down the middle. And then it's got you know that separation right here, almost looks like a fracture between the top or the front of the nasal bone and the side to side plane, then it steps almost kind of to a front again, and then like a little corner piece, and that's the part that has the most questions in it because it's not clear. Like I said, it's not clear where the front of the nose becomes the side of the nose.

Where does it become the front part of the cheek, the front part of the face again? Just Where is that? Okay, so let's keep looking here. We're gonna look on some real people. This part here is what we're talking about front part of the nose, front plane, step down on side plane, and then there's this right here. Right?

That's that inner part of the orbital eye socket. Okay, and here's, on the far side, we see the nasal passage. So that's accommodating the airflow right into the nose into the nostrils. And it goes through these passages here. So you see that little bump out there. Okay.

On this guy, we see it really clear, front plane, side plane. And you can see the cast shadow describes it well. Right? There's that real clear corner. But here, it's not so much, it's a lot smoother. And so if we know where the rhythm of the nose is, that really helps define, you know, this area for us.

Right because there's a front plane. plane of the cheap side plane of the nose, front plane of the nose, okay. Okay, let's check it out here. You can see it on here. Pretty good. She's got a real kind of bumpy part of that neighs Alice or the nasal bone.

Going into that maxilla right. And then you See the eye socket. So there's nasal bone right here. That's one, then two is this part here? Which is that maxilla. And then three is the eye socket.

So that's stuff we should get familiar with. Otherwise, our noses just look like they're stuck on, or the connection between the eye and the nose. And the glabella doesn't look valid or authentic. And people start to question it and we question it. Right. So we see here, the eye socket.

Right And then we've got the front plane. Step down, side plane right into there. nasal passage here held in check by the Allah wing or that fat, the fatty tissue of the nose. And then here the the glabella the Keystone once you know that little Keystone and how that connects, the browser connects the nose and this this area in here, you've got it figured out. Okay? And the mysteries over problem solved, right?

Okay, so let's go over here and we'll just look at it real quick again. You can see labella which is kind of a downplaying downturn plane. And then you've got the the front nasal bone. And it's not the whole piece here. It's just this part. Right here's the cabin.

Of the nasal bone that's covered by cartilage. Okay. There's that piece of cartilage that fits. Right in here. It's like a triangular piece of cartilage that septum right that's in there, that thin piece of cartilage. All right.

And then the that eye socket. It's a tricky part because it's zoom in here a little bit. nasal bone, nasal bulb. eye socket, right. That's that little bump. Oftentimes shows up in shadow.

It's like a corner, corner piece of molding, like connecting this, the wall to the ceiling, you'll see those old molding right so there's a bump right here. And then it goes into the eye socket and of course, the eyeball is here covering a lot of that, but you will see a little bit in here. Okay. And you'll see all this stuff. Another part, there's that rhythm of the nose. Let's see, let's go from bring this out that rhythm of the nose is so good to know.

Here like this, can see how the nasal passage is following along here on the far side, right and then on this side right adjacent to The nasal bone, okay, and that's part of the maxilla. So rhythm of the nose from side to side. Good to know. So there's your maxilla extend extends all the way down side of the nose all the way down to the teeth, the upper teeth, okay, and this is the zygomatic arch right there. Okay, from talus or the frontal bone. And that's pretty much all we need to know.

You can see that that cartilage is going to come out and then you'll have the fatty tissue of the all our wing going into the cartilaginous part under here is the septum of the nose dividing the two air holes. Right. And then here, if we get to front position here is where the philtrum is the philtrum. It's kind of that teardrop shape. It's got two creases on left and right. And it's nestled in to the upper lip.

Right so the red portion of the lip there So there's the red muscle portion of the lips. And yes, the philtrum is right in there. Alright, so we've connected the forehead, the eyes, right forehead, eyes, nose, and mouth areas all together, right? So they're all connected to each other. And that's gonna make for a really good solid drawing. Okay, so let's go ahead and do the nose drawing demo.
