Primary Olfactory Cortex


We just learned about the Olfactory Bulb.

Another part of the way humans smell is the Primary Olfactory Cortex.

This is the last part of the brain that takes the messges from the Olfactory Bulb, figures out what the smell is that you are smelling, and tells the rest of your brain whether it is a good smell or a bad smell!

Olfactory Bulb


We just learned about the Olfactory Receptor Neuron.

Another part of how noses work is the Olfactory Bulb.

This is a part of the brain right in the front that takes the messages from the Olfactory Receptor Neuron.
The neuron sends messages to the bulb, and the bulb figures out what the smells mean and sends those messages to the rest of the brain so you know what you are smelling.

Olfactory Receptor Neuron


We just learned about the Olfactory Receptor.

Another part of the nose is the Olfactory Receptor Neuron.

The word "olfactory" means something to do with the sense of smell.
In Latin the word olere later turned into the English word odor, so olfactory means something like the smells factory.

The Olfactory Receptor we already learned about is where smells come in and get turned into messages for the brain.
The Olfactory Receptor Neurons are what take those messages from the Receptors and pass them on to the brain to understand what smells you are smelling.

Olfactory Receptor


We just learned about the Olfactory Mucosa.

Another part of the nose is the Olfactory Receptor, also called odorant receptors or just OR.

These are tiny little parts of cells in the nose that sit and wait for smells to come in.
There are tiny little hairs called cilia that these cells are in, just waiting for something to smell.

If a smell comes in, it will be made up of some chemicals.
Each olfactory receptor is built to handle a different type of smell.

When a smell like a flower comes in, that will bring flower smelling chemicals into the nose, and the receptors that are waiting for flower smells will get excited and let out other chemicals that tell the brain which kind of smell just came in.

Olfactory Mucosa


We just learned about the Vomeronasal Organ.

Another part of the nose is the Olfactory Mucosa.

This is the wet skin on the inside of the nose that helps collect the things in the air that make smells.
The mucosa is like the inside of your mouth, and is wet and slimy.
Those smells stick to the wet slimy skin, and then some other sensors in the nose work to figure out what the smell is.

Vomeronasal Organ


We just learned about the .

Another part of the nose is the Vomeronasal Organ.

This is back behind the nose and above the mouth, and is where all of the smells end up for your nose to smell.
The vomeronasal organ has some things called "receptors" that can tell when there are different types of chemicals in the air.
When those receptors sense the chemicals, they tell your brain that they are smelling something.

Sphenoethmoidal Recess


We just learned about the Nasal Meatus.

Another part of the nose is the Sphenoethmoidal Recess.

This is a place in the back of the inside of the nose that connects to the sinus.
The sinus is where the mucus comes from, which is sometimes called things like snot or boogers.

Nasal Meatus


We just learned about the Nasal Concha.

Another part of the nose is the Nasal Meatus.

Remember that the concha are like shelves inside the nose that help split up the air to go into different paths.
The meatus is the paths that the concha sends the air into.

Nasal Concha


We just learned about the Choana.

Another part of the nose is the Concha.

Inside the nose, the concha are long bony shelves that help split up the air coming in so the air comes in nice and steady.

Part of this nose has some nerves and blood vessels coming in that some people think are the cause of brain freeze.

Choana


We just learned about the Vomeronasal Cartilage.

Another part of the nose is the Choana, also called the posterior nasal apertures or internal nostrils.

This is the part of the nose that is behind the nostrils, where the nose meets the throat.
You can breath through either your nose or your mouth, meaning that your throat or trachea is connected to both your nose and mouth.

The spot where the throat meets the nose area is the choana.

Vomeronasal Cartilage


We've now learned about 4 different types of cartilage in the nose: Septal Nasal Cartilage in the middle, Lateral Nasal Cartilage on the outside upper part, Major Alar Cartilage the big flare out of the nostril, and the Minor Alar Cartilage the bottom of the nostril by the face.

The fifth and last of the nasal cartilages is the Vomeronasal Cartilage.

We leaned a while back that the vomer a bone that is part of your skull, behind your nose and above the roof of your mouth.

The vomeronasal cartilage is between the nose and the vomer, and helps support other parts of the nose that help you smell things.

Minor Alar Cartilage


We just learned about the Major Alar Cartilage.

Another part of the nose is the Minor Alar Cartilage.

This is a part of the nostril that touches back to the face, and helps shape the nostril.

Major Alar Cartilage


We just learned about the Lateral Nasal Cartilage.

Another part of the nose is the Major Alar Cartilage, also called the greater alar cartilage or lower lateral cartilage.

This is another thin piece of cartilage that helps form the shape of the nose.
The major alar cartilage makes the upper outside part of the nostril, and also bends around at the tip of the nose and makes part of the inside part of the nostril right at the middle.

Lateral Nasal Cartilage


We just learned about the Septal Nasal Cartilage.

Another part of the nose is the Lateral Nasal Cartilage.

This is a flat triangle shaped cartilage on either side of the nose, that helps give the nose shape and protect the inside of the nose.

Septal Nasal Cartilage


We just learned about the Perpendicular Plate of Ethmoid Bone.
A while back we learned about the Vomer bone that is part of the skull right behind where the nose is.

Another part of the septum of the nose is the Septal Nasal Cartilage.

This is the part that sticks out from the perpendicular plate, and is made of rubbery cartilage that you can push around.
It is covered up by skin and other parts of your nose, and makes up the middle that separates your nostrils.

Perpendicular Plate of the ethmoid bone


We just learned about the Nasal Septum.

Another part of the nose is the Perpendicular plate of the ethmoid bone.

The ethmoid bone is the flat bone between the main part of the skull and where the nose is.
The perpendicular plate is attached to the ethmoid bone, and sticks out forward and splits the nostrils into two sides.

Nasal Septum


We just learned about the Nostril.

Another part of the nose is the Nasal Septum.

This is what splits the nose into a left and right nostril.
It is made up of different parts, with some of it cartilage and some of it bone.

Sometimes if there is a nose injury a person can have what is called a deviated septum.
In that case the septum in the middle gets removed and they would only really have one big nostril.

Nostril


We just learned about the Wing of the Nose.

Another part of the nose is the Nostril also called the naris.

The nostrils are the holes in the front of the nose, right above the mouth.
We use our nostrils for breathing in, breathing out, for blowing our nose when it gets stuffed up, and for smelling food.

The nostrils on the outside of the face are called the external nostrils, or anterior nares.
There are actually other nostrils further inside your nose that help bring the air and smells into your body.

Some people can actually flare out their nostrils, and make the holes get bigger and smaller!
Inside the nostril are around 1,000 hairs, and maybe if you have a stuffed up nose there might be nasal mucus (sometimes called snot) or dried nasal mucus (sometimes called boogers).

Wing of the Nose


We just learned about the Nasal Ridge.

Another part of the nose is the Wing of the Nose also called the Ala of the Nose.

This is the lower part of the nose that spreads out wide where the nostrils are, almost like a wing shape.
The word "ala" is Latin and means "wing".
