Vestibule of mouth:-where exactly is it ?

[gracy]

vestibule is a part of the mouth bounded anteriorly and laterally by the lips and the cheeks, posteriorly and medially by the teeth and/or gums, and above and below by the reflections of the mucosa from the lips and cheeks to the gums.I can't find it ?

this picture does not really justify the location described above !

Close your lips - puff up your cheeks with air. All of the parts that now stick out - your cheeks and lips - do so because you enlarged the vestibule. All of the stuff from teeth inwards and from teeth backwards don't take more space == oral cavity.

And your cheeks - anything outside of your: gums + teeth. This outside area fills with air when you do the puff trick above. You gums, teeth, are tongue are all insiders and not part of the vestibule -

If it helps - in English, the word vestibule is a Victorian word. In older houses. when you first enter via the front door, you go inside to a tiny entry room. People hang coats in there, and often stuff it full of potted plants. That is a vestibule. So tiny entrance volumes that lead to something else bigger inside are called vestibules.
