    • n glottis In anat, the mouth of the windpipe; the opening at the top of the larynx; the chink, cleft, or fissure between the vocal cords. It closes to a slit-like opening during phonation, through the approximation of the vocal cords. The term designates most strictly the opening itself, sometimes distinguished as rima glottidis, but is also applied to the opening with the contiguous limiting structures, as in the expression' œdema of the glottis, much as the term ‘mouth’ is used so as to include the lips. The ventral or anterior portion of the glottis, called glottis vocalis, is bounded by the true vocal cords; the dorsal or posterior part, glottis respiratoria, by the internal margins of the arytenoid cartilages.
    • n glottis The reed or tongue of certain ancient musical instruments.
    • n glottis In ornithology, an old name of the greenshank; subsequently taken as the specific name of the same, Totanus glottis; made by Koch in 1816 the generic name of the same, Glottis chloropus.

Voicing, or the phonatory process, occurs when air is expelled from the lungs through the glottis (the space between the vocal folds), creating a pressure drop across the larynx (also commonly called the voice box or vocal tract which houses the vocal folds).
