[ 1 ] At a mucocutaneous junction, epithelium transitions to epidermis , lamina propria transitions to dermis , and smooth muscle transitions to skeletal muscle . [ 2 ]
A nasal vowel is a vowel that is produced with a lowering of the soft palate (or velum) so that the air flow escapes through the nose and the mouth simultaneously, as in the French vowel /ɑ̃/ or Amoy [ɛ̃].
