V.  Analysis of the height of lingual vallates papillae in brazilian individuals.  Int. J. Morphol., 24(1) :39-42, 2005. SUMMARY: The vallates papillae lingual are located in the surface of the tongue in a area denominated of V lingual and itpresents cells gustatory gathered in gustatory buttons. This research evaluated the height papilar in relation to the surface of the tongue of 519 lingual vallates papillae. 45 human tongue samples were selected, of both sexes, inside of the 40-50 year-old age group, obtainedfrom necropsias accomplished in the Service of Verification of Deaths (S.V.O.) of UFPE/Secretaria of Health of the state of Pernambuco,in the city of Recife. The samples were classified different height levels accordingly in relation to the surface of the tongue, not establishingthe exact height, where there was the predominance of the height above the lingual surface. KEY WORDS: Vallates papillae; Tongue; Anatomy. INTRODUCTION The tongue is the main sensorial organ of the palate.It is a structure that contain different types tactile andquimiosensorial cells (Temple et al ., 2002). In the surface of the tongue can be noted structures called lingual papillae, inwhich there are gustatory cells. Inside the oral cavity thegustatory papillae can realize the quimioreception throughthe contact with the saliva and other dissolved particles(Douglas, 2002). The gustatory papillae are projections of the lingual epithelium, in which there are morphologicalmodifications of the mucous membrane that permit toincrease the contact area between the tongue and the contentof the mouth (Williams  et al ., 1995).The vallate papillae are the greatest gustatory papillaeand collect saliva from epithelium to the terminal furrows(Yasuda & Tomita, 2002). In general, the gustatory papillaeare defined as protuberances in the surface of the tongue(Bullock et al. , 1991; Snell, 1999), but, particularly, thevallates papillae are described to be on the same level of thelingual surface (Avery, 2001; Katchburian & Arana, 1999).Bhaskar (1989); Katchburian & Arana confirmed that thesepapillae, really, are not salient in relation to the lingualsurface. Besides, this author showed that these papillae areinvolved for a deep circular furrow. On the other hands,Gartner and Hiatt (1999) described the occurrence of vallatespapillae submerged on the surface of the tongue.Jeppsson (1969) declared that the vallates papillae iscomposed of a separate central papillae for a furrow of thesurrounding wall and it increased the occurrence of indivi-dual variations with regard to the number of these papillae,size and form.Are the papillae vallates in same plane, above orsubmerged in the lingual surface? This is a very interestingquestion that we will try answer in this paper. *  Prof. of the Department of Social Medicine of the Center of Health of the Federal University of Pernambuco /Recife/ Brazil. **  Prof. Doctor of the Department of Morphology and Animal Physiology, Area of Anatomy of the Rural Federal University of Pernambuco/Recife/Brazil. ***  Prof. Doctor of the Anatomy of the Center of Biological Sciences of the Federal University of Pernambuco/Recife/Brazil. ****  Prof. Doctor of the Area of Pharmacology of the Department of Morphology and Animal Physiology of the Rural Federal University of Pernambuco/Recife/Brazil. *****  Prof. Doctor of the Department of Pathological Anatomy of the Center of Sciences of the Health of the Federal University of Pernambuco/Recide/Brazil. ******  Monitors of Anatomy of the Department of Morphology and Animal Physiology of the Rural Federal University of Pernambuco/Recife/Brazil.  40 MATERIAL AND METHOD 519 lingual vallates papillae were removed of 45human tongues obtained after the realization of necropsiesin cadavers of both sexes and with ages between 40-50years old, in the Service of Verification of Obits (SVO) of the Federal University of Pernambuco (UFPE), Brazil.All the vallates papillae were removed of the areaof the V lingual of cadavers autopsied until 24 hours afterthe obit. After the collect and wash for removal of theadherent debris, the material was submitted to the fixationin 10% formaldehyde and stored to room temperature, inglass container, for a minimum period of 24 hours.The vallates papillae were classified in accordancewith the height papillary in relation to lingual surface inthree groups: A. Height papillary above of the lingualsurface; B. Height papillary in the same level of the lingualsurface; C. Height papillary bellow of the lingual surface. RESULT The Figure 1 shows the photographies of the vallatespapillae of the three groups. In first photography can beobserved that the vallates papillae are projected in relationof the lingual surface (Group A). The second and thirdphotographies disclose, respectively, vallates papillae onthe same level (Group B) and bellow (Group C) of thelingual surface. The distribution of the lingual vallates papillae heightsin the three groups, was the following: 459 (88.4%) had aheight papillary above of the lingual surface (Group A); in49 (9.4%) the height papillary was in same level of the lingualsurface (Group B) and in only 11 (2.1%) the height papillarywas bellow of the lingual surface (Group C). DISCUSSION The results found in this work showed that thevallates papillae are, in 88.4 % of the cases studied, weresituated above of the lingual surface. These results arecontrary that of Bhaskar, Avery and Katchburian & Aranasuggested that the vallates papillae lacated in the same levelor below in relation to lingual surface. Already being rarethe vallates papillae lingual below the level epitelial. Thislowers frequency contradicts the opinion of Gartner & Hiattwhen they referred that the vallates papillae is submergedin the surface of the tongue. Fig. 1.

F. & DE MELLO, R. J. V.  41 The establishment of the height papilar above thelingual surface increases the area of contact of the mucousmembrane papilar with the content of the oral cavity(Williams et al.  and Yasuda & Tomita), where the probabilityof having contact with the saliva and their dissolved particlesis very larger (Douglas, 2002).We didn't find authors mentioning the vallates papillaeabove the level of the lingual surface. The comments were just in relation to the lingual papilae in general if they standout above the epithelium, but not referring from a specificway to the height of the vallates papillae (maybe for seeminglogical). The height of the vallates papillae lingual has beenlittle study object, analysis or comment, as we could obser-ve in the reviewed literature. In general the goods stop todetail the microscopic part of the papillae lingual vallatesmore thoroughly, making little mention to the macroscopicpart.In this last case, the form parameters and of thenumber of these papillae, as well as of his/her location infront of the lingual V are the macroscopic characters moreapproached. Regarding the size (no specifically the height),they just mention that such papillae can vary, but thatexternally present the same characteristics and they arecomposed of a separate central papillae for a furrow of thesurrounding wall (Jeppsson).Are the papillae vallates in same plane, above orsubmerged in the lingual surface? Now is possible to answerthat the vallates papillae in Brazilian individuals are in 88.4%of the cases studied above of the tongue surface.Fig. 2.

RESUMEN: Las papilas valadas linguales están localizadas en la superficie dorsal de la lengua, en un área denominada Vlingual y presentan células gustativas acumuladas en botones gustativos. Se evaluó la altura papilar en relación con la superficie de lalengua de 519 papilas valadas linguales. Fueron seleccionadas 45 lenguas humanas, de individuos de ambos sexos, de 45 a 50 años deedad, obtenidas de autopsias del Servicio de Verificación de Óbitos de la Universidade Federal ed Pernambuco /Secretaría de Salud delEstado de Pernambuco, Recife, Brasil. Las muestras fueron clasificadas de acuerdo a los niveles de altura en relación con la superficie dela lengua, no estableciéndose la altura exacta, donde hubo predominio de papilas ubicadas sobre la superficie lingual.
