Clicks appear more stop-like ( sharp / abrupt ) or affricate-like ( noisy ) depending on their place of articulation: In southern Africa, clicks involving an apical alveolar or laminal postalveolar closure are acoustically abrupt and sharp, like stops, while labial, dental, and lateral clicks typically have longer and acoustically noisier releases that are superficially more like affricates.

The five click releases with dedicated symbols in the International Phonetic Alphabet ( IPA ) are labial, dental, palato-alveolar or " palatal ", ( post ) alveolar or " retroflex ", and alveolar lateral.

A language which displays the full range of stops and laterals is Kalkutungu, which has labial p, m ; " dental " th, nh, lh ; " alveolar " t, n, l ; " retroflex " rt, rn, rl ; " palatal " ty, ny, ly ; and velar k, ng.

A notable exception to the above generalizations is Kala Lagaw Ya, which has an inventory more like its Papuan neighbours than the languages of the Australian mainland, including full voice contrasts:, dental, alveolar, the sibilants ( which have allophonic variation with and respectively ) and velar, as well as only one rhotic, one lateral and three nasals ( labial, dental and velar ) in contrast to the 5 places of articulation of stops / sibilants.

However, ISO 15919 provides guidance towards disambiguating between various anusvara situations ( such as labial versus dental nasalizations ), which is described in the table below.

* physiology: head / capital, ear / aural, tooth / dental, tongue / lingual, lips / labial, neck / cervical, finger / digital, hand / manual, arm / brachial, foot / pedal, sole of the foot / plantar, leg / crural, eye / ocular or visual, mouth / oral, chest / pectoral, nipple / papillary, brain / cerebral, mind / mental, nail / ungual, hair / pilar, heart / cardial, lung / pulmonary, bone / osteotic, liver / hepatic, kidney / renal, blood / sanguine.

A common feature is that there are only voiceless and no voiced stops, while there is a set of voiced ( but no voiceless ) non-sibilant fricatives with the same places of articulation ( labial, dental, palatal, and velar ; in Yukaghir, Chukotko-Kamchatkan and Eskimo – Aleut also uvular ).

The labial fricatives often — perhaps usually — have lateral airflow, as the lip blocks the airflow in the center, but nonetheless they are not considered lateral consonants because no language makes a distinction between the two.

When lesions involve other oral mucosa in addition to the dorsal and lateral tongue, the condition is called migratory stomatitis ( or ectopic geographic tongue ); in this uncommon condition, lesions infrequently involve also the ventral tongue and buccal or labial mucosa, the soft palate and floor of the mouth.

In Korean hangul, however, all four labial consonants are based on the same basic element.

When labial pits are present, these are located between the scales as opposed to on them.

By contrast, the language has only two phonemically distinct vowels — which, however, have several allophones depending on the palatal and / or labial quality of adjacent consonants.

The crown is large and conical, very convex on its labial surface, a little hollowed and uneven on its lingual surface, and tapering to a blunted point or cusp, which projects beyond the level of the other teeth.

The dorsum of the head is shiny black, the upper and lower labial scales are white with black markings on the anterior edge of the scales.

* Gelechioidea Head smooth-scaled, labial palps usually are slender, recurved, with the terminal segment long and pointed ; the long proboscis bears scales on basal half.

* Pyraloidea Head rough-scaled, proboscis scaled, tympanal organs on abdomen ; labial palps usually not recurved, terminal segment usually blunt.

* Tineoidea Head often with tufty erect scales ; labial palps usually have bristles on middle segment and terminal segment is long ; wings usually held over back in tent-like position and head close to surface ; tineids often run fast

There are four cusps in the lingual row ( on the side of the tongue ) and three in the labial row ( the side of the lips ).

They have a wide caudal fin and two rows of labial teeth on the top of the mouth and four rows on the bottom.

Macroscopically, these lines can be seen on the labial surface or lip side of anterior or front teeth as horizontal lines on the tooth crown, also known as " imbrication lines ".

This is due to the effect that rounded back vowels have on, giving it velar and labial characteristics making an allophone of before these vowels ; the true phonetic then eventually became perceived as this allophone of and no longer a phonologically distinct speech sound.

Scattered clicks are found in ideophones in other languages, such as Kongo, Mijikenda, and Hadza ( Hadza does not otherwise have labial clicks ).

In other aspects, the pronunciation of hanja is more conservative than most northern and central Chinese dialects, for example in the retention of labial consonant codas in characters with labial consonant onsets, such as the characters 法 ( 법 beop ) and 凡 ( 범 beom ); the labial codas existed in Middle Chinese but do not survive intact in most northern and central Chinese varieties today.

These snakes lack the heat sensitive pits between the labial scales that most other python species have.

Some surgeries are needed for discomfort occurring from chronic labial irritation that develops from tight clothing, sex, sports or other physical activities.

These react with a secretion from the labial gland upon autothysis to form a mixture which is toxic to other termites.

A consonant may be placed between consonants in a consonant cluster where the place of articulation is different ( e. g., where one consonant is labial and the other is alveolar ).

It supplies the lips by its superior and inferior labial branches, each of which bifurcate and anastomose with their companion artery from the other side.

* Then there are the labial clicks, written with a bull's eye,.

The labial click is different from what many people associate with a kiss: the lips are pressed more-or-less flat together, as they are for a or an, not rounded as they are for a.

Five places of articulation are postulated for the consonant inventory of proto-Niger – Congo: labial, alveolar, palatal, velar, and labial-velar.

Unlike the passive articulation, which is a continuum, there are five discrete active articulators: the lip ( labial consonants ), the flexible front of the tongue ( coronal consonants: laminal, apical, and subapical ), the middle – back of the tongue ( dorsal consonants ), the root of the tongue together with the epiglottis ( radical consonants ), and the larynx ( laryngeal consonants ).

However, there are exceptions: Colloquial Samoan lacks the coronal, and several North American languages, such as the northern Iroquoian and southern Iroquoian languages ( i. e., Cherokee ), lack the labial.

In the Latin alphabet, this is accidentally the case with the letters " b " and " p "; however, labial " m " is completely dissimilar, and the similar-looking " q " and " d " are not labial.

Some languages, such as Japanese and perhaps the Northern Iroquoian languages, have a sound typically transcribed as where the lips are compressed ( or at least not rounded ), which is a true labial – velar ( as opposed to labialized velar ) consonant.

Truly doubly articulated labial – velars occur as stops and nasals in the majority of languages in West and Central Africa ( for example in the name of Laurent Gbagbo, former president of Ivory Coast ; they are found in many Niger – Congo languages as well as in the Ubangian, Chadic and Central Sudanic families ), and are relatively common in the eastern end of New Guinea.

In the early twentieth century it was argued that the labella are the modified labial palps, and that point of view still is seen as having merit.

** Veneers — artificial coverings similar to above, except that they only cover the forward ( labial or buccal ) surface of the tooth.

Micronesian languages are known for their lack of plain labial consonants ; they have instead two series, palatalized and labio-velarized labials.

Clicks are doubly articulated by definition: they involve a coronal ( more rarely labial ) forward articulation, which defines the various ' types ' of clicks and the IPA letter assigned, plus a dorsal closure that pulls double duty, both as the second place of articulation, and as the controlling mechanism of the lingual ingressive airstream.

It also has more prominent labial folds and longer digits than those of P. labiata.
