Sublingual Caruncle

We just learned about the Fimbriated Fold.

Another part of the mouth is the Sublingual Caruncle.

Sublingual means "underneath the tongue", and caruncle means some skin sticking out like a bump.

Remember the frenulum is the piece of skin under the tongue that holds it in place.
On each side of the frenulum is a little bump.
That bump is the sublingual caruncle, and it is where most of the saliva or spit in your mouth comes out of.

Fimbriated Fold

We just learned about the Frenulum.

Another part of the mouth is the Fimbriated Fold of the tongue, also sometimes called the Plica Fimbriata.
The word fimbria comes from the latin word for "fringe"
These are two folds of skin on the bottom of the tongue, going front to back on either side of the frenulum.

For most people these just look like lines with bumps going down the tongue, but for some people there are small pieces of skin sticking out longer.

Frenulum

We just learned about the Foramen Cecum.

Foramen Cecum

We just learned about the Sulcus Terminus.

Another part of the tongue is the Foramen Cecum.

Remember the median sulcus is the line that goes down the middle of your tongue.
At the back of your tongue, and at the end of that line is the foramen cecum.

We also learned that the sulcus terminus is a v shape at the back of the tongue.
In the middle of the v shape is the foramen cecum.

So right where the "median sulcus" line and "sulcus terminus" v shape meet is the "foramen cecum" point.

Sulcus Terminus

We just learned about the Median Sulcus.

Another part of the human tongue is the Sulcus Terminus.

This is all the way on the back of the tongue.
Right before the back of the throat, some of the skin in the tongue makes a V-shape,
that comes to a point in the middle right at the end of the median sulcus before going down the throat.

This is called the sulcus terminus.

Median Sulcus

We just learned about the Circumvallate Papillae.

Another part of the tongue is the Median Sulcus.

Right on the top middle of your tongue there is a line going all the way from front to back.

This line is the median sulcus, and it divides the tongue into a left and right side.
It's sort of like a line in a piece of paper that's been folded, and most people can fold their tongue in half right there inside their mouth.
With the tongue folded right on that line, sometimes it can help when eating food.

Circumvallate Papillae

We just learned about the Foliate Papillae.

Another part of the mouth is the Circumvallate papillae.

We know the filiform papillae are just for touch,
the fungiform papillae have taste buds,
and the foliate papillae are soft folded skin on the sides and back of the tongue with taste buds.

The circumvallate papillae are rounded on top, and the tongue has around 8 to 12 of them.
They are on the back part of the tongue, with one row on each side.
These papillae are usually bigger bumps than the other types of bumps on the tongue.

Foliate Papillae

We just learned about the Fungiform Papillae.

Another part of the mouth is the Foliate Papillae.

So we know the filiform papillae are just for touch, and the fungiform papillae have the taste buds.

The foliate papillae are on the back and sides of the tongue, and almost look like they have folds on them.
They are soft, and don't have any keratin, but they do have taste buds on them.

Fungiform Papillae

We just learned about the Filiform Papillae.

Another type of lingual papillae is the Fungiform Papillae.

Remember the lingual papillae are the bumps on the top of your tongue, and there are a few different types.

The fungiform papillae are shaped like a club, and are usually red.
They are mixed in along with all of the filiform papillae, but they are mostly found on the tip and sides of the tongue.

These bumps have taste buds, and can sense the five different tastes: sweet, sour, bitter, salty, and umami.

Filiform Papillae

We just learned about the Taste Buds.

Another part of the tongue is the Filiform Papillae.

The lingual papillae that we learned about come in a few different shapes and sizes.
One of those is the filiform papillae, which are small and cone shaped, with small threads at the top.

These papillae do not have any taste buds, they are only used by the tongue for feeling, and to give the tongue a rough feeling.

The tongue has more filiform papillae than any other type of papillae.

Taste Buds

We just learned about the Lingual Papillae.

Another part of the mouth is the Taste Buds.

The lingual papillae are the little bumps on the tongue, and on most of those little bumps are what we call taste buds, or taste receptors.

The taste receptors or buds are the tongue are what tell your mouth what flavor something is.
There are five different taste types: salty, sour, bitter, sweet and umami.

The human tongue usually has from 2,000 to 8,000 taste buds.

Lingual Papillae

We just learned about the Specialized Mucosa.

Another part of the mouth is the Lingual Papillae.

These are the little bumps on the top of your tongue that are where your taste buds are.
The way the tongue has these little bumps helps your tongue be able to taste all sorts of different flavors.

Specialized Mucosa

We just learned about the Lining Mucosa.

This is the skin on the top of the tongue that makes up the taste buds that tell you what something tastes like!

Lining Mucosa

We just learned about the Masticatory Mucosa.

Another part of the mouth is the Lining Mucosa.

This is the part of the soft loose skin inside of the mouth under the tongue, on the inside of the cheeks, and on the inside of the lips.

Masticatory Mucosa

We just learned about the Oral Mucosa.

Another part of the skin in the mouth is the Masticatory Mucosa.

This is the part of the wet mouth skin called gingiva that is on the roof of the mouth, and the top of the tongue.
The skin on these parts of the mouth is called keratinized stratified squamous epithelium.
That is a lot of big words that mean flattened skin with a lot of layers, that isn't loose and saggy.

It is different than other skin like underneath the tongue that is very loose.

Oral Mucosa

We just learned about the Gingiva.

Another part of the mouth is the Oral Mucosa.

This is a fancy way of saying the wet skin inside your mouth.
The oral mucosa is the skin on the inside of your cheeks, your gums, the skin on the roof of your mouth, on your tongue, under your tongue and the skin inside your lips.

Gingiva

We just learned about the Periodontal Ligament.

Another part of the mouth is the Gingiva, also known as the Gums.

The gums are the soft part of the inside of the mouth, around the teeth.

The lips and cheeks have skin that moves around, but the skin of the gums stays stuck to the bones of the jaw, so they help hold the teeth in place and help protect the parts of the teeth below the gums.

Gums are supposed to be a color called "coral pink" for lighter skinned people.
If the gums are red or bleeding, it can mean that the person has bad mouth problems and needs to brush more or use mouthwash.

Another part of the mouth is the Periodontal Ligament, sometimes just called the PDL.

We learned that the tooth sits into the tooth socket bone.
The Periodontal Ligaments is a soft tissue that helps hold the tooth in place, and goes between the tooth cementum and the tooth socket.
