thyroartenoid
These are the muscles that form the body of the vocal folds themselves.
They shorten the vocal folds by pulling the arytenoid from the back end of the vocal folds toward the thyroid which is the front end.
This shortens the vocal folds and bunches them up, which causes them to vibrate more slowly, thus lowering pitch.
The thyroarytenoid muscles also have a force to strengthen glottic closure.
A glottic stop is a stop consonant, without release, having a secondary articulation. As in yep for yes, nope for no.
They help bring the vocal folds together and keep them together to resist the airstream from the lungs.
