An chnámh uachtarach is an chnámh íochtarach atá timpeall ar an mbéal agus a choinníonn na fiacla. Bíonn an chnámh uachtarach, an mhascaill, greamaithe go docht leis an aghaidh, agus gluaiseann an chnámh íochtarach, an mandabal, ina coinne. Gluaiseann na gialla i gcoinne a chéile le linn cogaint is meilt bia. Gluaiseann an mandabal le linn urlabhra freisin.[1]
