==Nares==

Nasal [[Salt gland|salt glands]] are present in [[Lizard Feeding|herbivorous]] [[Lizard Classification|iguanid]] lizards such as the [[Green Iguana|green iguana]]. These excrete excessive [[Sodium|sodium]] and [[Potassium|potassium]] when the plasma osmotic concentration is high. Lizards achieve this by sneezing, which expels a clear fluid that dries to a fine white powder consisting of salts. This mechanism should not be mistaken for a upper respiratory infection as it is a normal physiologic process allowing water conservation. Anterior in the roof of the mouth, the paired internal [[Lizard Physical Examination|nares]] are a common site for discharges to accumulate and therefore a good sampling site for bacteriology when a respiratory infection is present or suspected.

==Glottis==

==Glottis==

It is normally closed except during [[Lizard and Snake Respiration|inspiration or expiration]]. The hard palate is reduced to allow airflow from the inner nasal opening to the glotttis. The [[Lizard Physical Examination|glottis]] is generally quite rostral and located at the base of the tongue. This simplifies intubation and tube-feeding.
