This includes the pharyngeal consonant pharyngeal , epiglottal consonant epiglottal , and epiglotto pharyngeal consonant epiglotto pharyngeal places of articulation, though technically epiglottal consonants take place in the larynx . The term radical was coined to help disambiguate pharyngeal , which had come to mean any consonant articulated in the throat, whether the articulator was the back of the tongue high pharyngeals or the epiglottis low pharyngeals . However, the term pharyngeal is still commonly used in the broader sense, and authors such as Miller 2005 prefer guttural , which may include glottal consonant s as well.

Whereas with a flap or tap , a specific gesture is used to strike the active articulator against the passive one, in the case of a trill the articulator is held in place, where the airstream causes it to vibrate. Usually a trill vibrates for 2 3 periods , but may be up to 5, or even more if geminate consonant geminate . However, trills may also be produced with only a single period.

Pharyngeal jaws are a second set of jaw s contained within an animal s throat, or pharynx , distinct from the primary oral jaws.

File Pharyngeal jaws of moray eels.svg thumb 300px The pharyngeal jaws of the moray eel Although approximately 30,000 species of fish es are known to have pharyngeal jaws, in many species having their own teeth, the most notable example of animals possessing them is the moray eels of the family Muraenidae . Unlike those in other fishes known to have them, those of the moray are highly mobile. This is possibly a response to their inability to swallow as do other fishes by creating a Suction negative pressure in the mouth, perhaps induced by their restricted environmental niche burrows . Instead, when the moray bites prey, it first bites normally with its oral jaws, capturing the prey. Immediately thereafter, the pharyngeal jaws are brought forward and bite down on the prey to grip it they then retract, pulling the prey down the moray eel s gullet, allowing it to be swallowed. ref name Mehta2007 cite journal last Mehta first Rita S. authorlink Rita Mehta coauthors Peter C.
