How can only one cheek be inflated with air?

1.13K 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.

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