How can only one cheek be inflated with air?

1.11K viewsBiologyOther

There is no air tight barrier in between my two cheeks, so how am I controlling the air in my mouth and directing it to one specific cheek? The deflated cheek is still floppy, so it’s not like I’m tensing a muscle to stop it inflating.

Also works if I have a mouth full of water, and can also be directed to top and bottom lips.

Thank you.

Tried it myself, definitely using cheek muscles. Cheeks are just naturally soft and squishy, which is why it feels like your cheeks are still “floppy” from the outside.

You can feel it if you put a finger inside your mouth and do the same “putting air in one cheek but not the other” thing. One cheek is definitely tensed on the inside.

All at once, a bunch of people around the world just started puffing out their cheeks, scientifically.

It’s not floppy. what you’re feeling is the buccal fatpad. Your tensing the opposite side muscles to keep them from ballooning.

After a minute of shifting a mouthful of air from one side to the other, your non-inflated cheek is more “flexed” than you realize. It doesn’t take much to not inflate, so while it doesn’t feel like you’re consciously flexing the cheek to keep it un-inflated, you are keeping it taut.

When I do this and pull on the deflated cheek I can feel that it’s seeled / pulling a vacuum. Also true when my nose airway is open.

So I wouldn’t exactly say it’s floppy and that you’re using no muscles to do it

Feel your cheeks before you inflate either of them. The muscles are relaxed. Now inflate on cheek and feel the other on. It is tense, not very tense, but tense enough to keep from inflating.

The muscles on the inflated side are relaxed and the ones on the uninflated side are tensed. The air/water goes to where there is less pressure.

Tongue strong

Tongue shove air to one side

Tongue pushes harder to keep air in cheek number one than air pushes to try and go to cheek number two

My mouth is sore from testing this out now 🙁

You have MUSCLESSS!! in your cheeks too , strong enough to push water or air to the side where you haven’t contracted them …

Both of mine are inflated right now

Just push your lips into duck lips and blow in both ways.
