| This study assessed the micro anatomical differences in the tongue of rat, bat and pangolin with a view to establishing the functional anatomical differences of these mammalian tongues on their dietary pattern. Ten rats, ten bats and ten pangolins were used for this study. The animals were sacrificed and the tongue excised and processed for light microscopical study adopting the following stains: Haematoxylin Eosin, Verhoeff Gieson and Masson trichrome. The results showed non papillation of the keratinized stratified epithelium of pangolin tongue unlike the papillation seen in the tongue of the rat and bat. While the filiform papillation seen in the rat was bristle like, the filiform papillae in the bat were crown-like. There was also an unusual dense... |

| The vallates papillae lingual are located in the surface of the tongue in a area denominated of V lingual and it presents 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, obtained from 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 establishing the exact height, where there was the predominance of the height above the lingual surface |

| The Laser used correctly in the medical practice offers clear advantages compared with traditional therapies. The improvement and even the elimination of many significant skin lesions can be achieved with reduced risks to patients. However, it is important to keep security measures and understand the possible effects on an experimental model. The chick embryo is a good model to evaluate the direct effects of non-ionizing radiation for its easy handling and availability. The purpose of this communication is to show our histological findings in organs of the chick embryo with and without protective barrier to be subjected to radiation excimer. We used the following issuers: intense pulsed light (excimer Xe-Cl laser of 308 nm wavelength). It was irradiated... |

| The dorsal surface of the tongue gustatory organs of Chinese fire-bellied newt (Cynops orientalis) was observed by employing the light and scanning electron microscopy (SEM) techniques. The results revealed that the rostral and median part of the tongue presents a round apex and covered by taste disks (TDs). They are usually roundish or ellipsoidal in shape and are 20-35 mm in diameter. The many openings of the lingual glands are 4-8 mm in diameter exist in the lateral border or median part of lingual body. The gustatory organs on the tongue did not differed form those presented in other species in Caudates. These may indicate the functions of gustatory organs on the tongue related to their life habit. |

| ABSTRACT The biological behaviour of the tumours vary according to the species in which they occur, its location within the cavity, clinical stage and histopathological nature. Lingual neoplasms are generally uncommon in companion animals. Rhabdomyosarcomas are malignant, solid, aggressive formations with high metastatic potential. The clinical signs are variable and a definitive diagnosis can only be reached through histopathological analysis of biopsy and necropsy specimen. In some cases, immunohistochemical study may be needed to confirm the diagnosis. This paper aims to highlight important points about this uncommon condition in dogs, using a case report of lingual rhabdomyosarcoma, which showed no evidence of metastasis after diagnosis, nor of local... |

| The lingual artery constitutes one of the branches of the external carotid artery, which is responsible for the vascularization of the tongue and neighbour regions. The hemorrhage caused by a lesion of the lingual artery can occur during a dental procedure (surgical accidents by the use of an instrument or rotating disc), by trauma, biopsy and dental implant. In some cases is difficult to stop the hemorrhage of injured vase, so is necessary to realize the extraoral ligature of this artery. Hence, this work studied the anatomic aspects of the lingual artery, by forty-eight dissections of twenty-four corpses settled in formol 10%, aiming to detail the origin, pathway and anatomic relations of the lingual artery in the region of anterior trigone of the neck,... |

| ABSTRACT This is the first report of parasitism by Gongylonema sp. in a free-ranging callitrichid from the Atlantic forest of Espírito Santo, Brazil. A juvenile male of Geoffroy's marmoset (Callithrix geoffroyi) was euthanized due to poor prognosis, then necropsied. Samples of the tongue were collected for routine histological processing. Microscopically, there were transversal sections of adult nematodes within the epithelial layer of the mucosa of the tongue. Lingual scraping demonstrated a small number of oval embryonated eggs with a thick capsule. The morphology of the adult parasites and the eggs, associated with its location, were compatible with the Spirurida nematode of the genus Gongylonema. Further studies are needed to evaluate the impact of... |

| The characteristics of intrinsic muscle fibers in the anterior third of the adult rat tongue were studied employing light microscopy, SEM and high-resolution SEM (HRSEM) methods. For light microscopy, specimens were fixed in Bouin's solution and embedded in paraffin. In order to identify the muscle fibers and bundles of collagen fibers, frontal sections were stained with hematoxylin-eosin, azo-carmin and picro-sirius. The results showed that muscle fibers near the lamina propria are fixed with connective tissue, constituting several groups. The bundles of muscle fibers are arranged in longitudinal, vertical and transversal directions. For SEM, specimens were fixed in modified Karnovsky solution and freeze-fractured in liquid nitrogen revealed the collagen... |

| The morphology of filiform papilla root in the tongue of Chinese yellow cattle were studied by scanning electron microscopy, and several geometric models were established to analyze the possible effects of such structures on lingual mechanical functions. Conical and tongue-like filiform papillae were detected in different locations on the lingual surface, along with six types of root structures. A lingual groove surrounded the papillae in five of these structures. To date, such grooves have not been discussed in studies on bovine lingual morphology, and those distributed on the dorsal surface of the lingual apex can limit the motion ranges of filiform papillae. Two secondary papillae emerged from a groove on the dorsal surface of the lingual apex's caudal... |

| The tongue is one of the most likely places for the primary squamous cell carcinoma (SCC) to arise in the western world.This work intends to do a morphometric evaluation of the cellular nucleus, as well as a morphometric analysis of the nucleolar organizer regions (NORs). The biopsy specimen was removed from patients with tongue SCC, staged T2N0M0, before they underwent treatment. They were, then, subject to hemiglossectomy and supraomohyoid neck dissection (SOHND) and presented different clinical evolution. According to that, they were subdivided in three groups: Group A, control group, formed by patients without tongue neoplasm (the histopathologic specimen was obtained from the Department of Pathology at Hospital de Base and Faculdade de Medicina de Sao... |

| The dorsal surface of the tongues of the Slow Loris and the Pygma Slow Loris were examined by employing scanning electron microscopy techniques. Three types of the papillae are present on their dorsal surface of the tongue: filiform, fungiform and vallate. The filiform papillae are located the apex and the body of the tongue, and we observed that each of them has a gustatory pore. The fungiform papillae, scattered singly among the filiform papillae, distribute mainly on the apex of the tongue. The vallate papillae are located along the diversing arms of the V-shaped boundary between the anterior and posterior regions of the tongue. In addition, no foliate papillae were observed. The morphological characteristics of the dorsal surface of the tongues in Slow... |

| The dorsal surface of the tongue of Zaedyus pichiy (Desmarest, 1804) was examined by scanning electron microscopy. Conical and branched filiform, fungiform and vallate papillae are described. No foliate papillae were seen. Conical filiform papillae are distributed in the apex, both lateral edges and caudally to the vallated ones. The branched papillae represent the most numerous type of lingual papillae; they are distributed over the entire dorsal surface of the tongue. The fungiform papillae are placed among the filiform ones, more densely distributed on the tip of the lingual apex. In the posterior third of the tongue there are two vallated papillae surrounded by a deep circular grove. Fungiform and circumvallate papillae are related to the sense of... |

| The dorsum of the tongue of Dasypus hybridus (Desmarest, 1804) studied by scanning electron microscopy, shows conical and branched filiform, fungiform and vallate papillae. No foliate papillae were seen. Conical filiform papillae are placed in the apex of the tongue and posterior to the vallated ones. Branched papillae are compactly distributed over the entire dorsal surface of the tongue. Fungiform papillae are more abundant on the first third of the tongue and they are distributed between filiform papillae. Only two vallate papillae were observed placed in the posterior third of the tongue, surrounded by a deep grove. The presence of taste buds on fungiform and vallate papillae indicate that both are involved in the sense of taste, while the filiform... |

| Traumatic ulceration of the ventral surface of the tongue is an uncommon condition in infants and toddlers, which is often associated with natal and neonatal teeth in newborns. The aim of this report is to present a case of bilateral ulcerative ulcers on the ventral surface of the tongue caused by the eruption of first primary mandibular molars in a 14-month-old male child. The child was able to point to the lesions and also refused to consume certain beverages and foods, which favored an early diagnosis. Clinical treatment consisted of manual smoothing of the sharp edges of both mandibular first molars and a home regimen of lidocaine hydrochloride solution (Xylocaine®, Astra) and a steroid solution of triamcinolone acetonide (Omcilon A, Brystol-Myers)... |
