Autores: Motoyama,Aracy A.; Watanabe,Ii-sei; Ogawa,Koichi.
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...

Autores: Xie,Zhaohui; Li,Jingting; Cheng,Pu.
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.

Provedor de dados: 77
Autores: Fu,Jun; Qian,Zhihui; Ren,Luquan.
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...

Autores: Lins,Carla Cabral dos Santos Accioly; Cavalcanti,Jennecy Sales; do Nascimento,Daniela Lira.
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...

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...
