Light and Scanning Electron Microscopic Study on the Tongue and Lingual Papillae of the Common Hippopotamus, Hippopotamus amphibius amphibius

THE ANATOMICAL RECORD : ADVANCES IN INTEGRATIVE ANATOMY AND EVOLUTIONARY BIOLOGY, Issue 7 2009
Ken Yoshimura
Scanning electron microscopic micrograph of the connective tissue core of fungiform papillae distributed in the dorsal surface of the tongue in the common hippopotamus (Hippopotamus amphibius amphibius). There are various kinds of lingual papillae distributed on the dorsal surface of the tongue among mammal species. It has been revealed that there were morphological differences found on each lingual papilla; filiform, fungiform, conical, foliate, and vallate papillae depend on the mammalian species, especially on the connective tissue cores beneath the epithelial surface. The fungiform connective tissue core of hippopotamus exhibited are quite similar to those found in the other artiodactyls; however, it lacked other typical morphological types of the lingual papillae found on the artiodactyl species. The unique mosaic-like morphological characteristics of the hippopotamus' lingual papillae may represent the unique evolutional or dietary background of this species.

Morphology and Morphometry of Lingual Papillae in Adult and Newborn Egyptian Fruit Bats (Rousettus aegyptiacus)

ANATOMIA, HISTOLOGIA, EMBRYOLOGIA, Issue 5 2009
J. Trzcieli, ska-Lorych
Summary The paper presents a comparison of the microscopic structure and morphometric traits of gustatory and mechanical lingual papillae in newborn and adult frugivorous Egyptian fruit bats (Rousettus aegyptiacus). All of the four types of lingual papillae found in adult animals were observed on the tongue surface in the newborn Egyptian fruit bats. After the birth, the gustatory papillae (fungiform and vallate papillae) were especially well-developed, as their structural characteristics, such as morphology of the epithelium and presence of the taste buds, indicate that they have reached almost complete functional traits. Mechanical papillae, particularly filiform papillae, in newborns are still fetal in character. Keratinization processes in the epithelium of these papillae are not advanced and specific structures, such as elongated processes, are missing. The morphometric analysis of the size of papillae and thickness of the mucosal epithelium showed that a complete development of keratinized structures in Egyptian fruit bats occurs at later stages of postnatal development.

Scanning Electron Microscopic Study of the Lingual Papillae in the Arctic Fox (Alopex lagopus L., 1758)

ANATOMIA, HISTOLOGIA, EMBRYOLOGIA, Issue 5 2009
H. Jackowiak
Summary This study aims to show the distribution and the three-dimensional structure of the lingual papillae in the arctic fox. The macro- and microscopic structure of the tongue and its lingual papillae was studied in 11 adult arctic foxes. Two types of mechanical papillae were distinguished on the dorsal surface of the tongue , filiform papillae and conical papillae. The gustatory papillae in the arctic fox are represented by fungiform, vallate and foliate papillae. The keratinized filiform papillae on the anterior part of tongue are composed of one big posterior process accompanied by 10,12 secondary anterior processes. The number of anterior processes of filiform papillae undergo a complete reduction within the area between the posterior part of the body of the tongue and area of the vallate papillae. The conical papillae cover the whole dorsal surface of the root of the tongue, including the lateral parts surrounding the area of the vallate papillae and the posterior part of the root. The size of the conical papillae increases towards the root of the tongue but their density decreases. In the arctic fox, there are three pairs of vallate papillae distributed on the plan of a triangle. The diameter of vallate papillae in each successive pair is bigger. The wall surrounding the body of the vallate papilla and its gustatory trench is composed of six to eight conical papillae joined at various degree. The foliate papillae on both margins of the tongue consist of seven to nine laminae. [source]

S. Emura
Summary The dorsal lingual surfaces of infant Japanese macaque (Macaca fuscata) and adult savanna monkey (Cercopithecus aethiopus) were examined by scanning electron microscopy. Filiform, fungiform, foliate and vallate papillae were found. The filiform papillae were distributed over the entire dorsal surface of the tongue. The fungiform papillae were round in shape, and more densely distributed on the lingual apex. The foliate papillae were seen on the dorsolateral aspect of the tongue. The three vallate papillae were arranged like a triangle with the apex of the triangle directing caudally. Each papilla was surrounded by a groove. The rudiments of the fungiform, foliate and vallate papillae were visible earlier than those of the filiform papillae. [source]

Abstract El-Bakry, A.M. 2010. Study by transmission and scanning electron microscopy of the morphogenesis of three types of lingual papillae in the albino rat (Rattus rattus).,Acta Zoologica (Stockholm) 91: 267,278 Tongues were removed from albino rat foetus on days 12 (E12) and 16 (E16) of gestation and from newborns (P0) and from juvenile rats on days 7 (P7), 14 (P14) and 21 (P21) postnatally for investigation by light, scanning, and transmission electron microscopy. Significant changes appeared during the morphogenesis of the papillae. At E12, two rows of rudiments of fungiform papillae were extended bilaterally on the anterior half of the tongue. At E16, the rudiments of fungiform papillae were regularly arranged in a lattice-like pattern. A rudiment of circumvallate papillae could be recognized. No rudiment of filiform papillae was visible. No evidence of keratinization was recognizable. At P0, rudiments of filiform papillae were visible but had a more rounded appearance, with keratinization. The fungiform and circumvallate papillae were large and their outlines were somewhat irregular as that found in the adult rat. At P7, the filiform papillae were large and slender. The fungiform papillae became large and the shape of circumvallate papillae was almost similar to that observed in the adult. At P14 and P21, the shape and structure of the three types of papillae were irregular as those found in the adult. In conclusion, the rudiments of the fungiform and circumvallate papillae were visible earlier than those of the filiform papillae. The morphogenesis of filiform papillae advanced in a parallel manner with the keratinization of the lingual epithelium, in the period from just before birth to a few weeks after birth. [source]

Morphological study of the lingual papillae of the giant panda (Ailuropoda melanoleuca) by scanning electron microscopy

JOURNAL OF ANATOMY, Issue 2 2008
J. F. Pastor
Abstract Due to the scarcity of giant pandas, there are few descriptions of their morphology and even fewer of their microscopic anatomy and the ultrastructure of their organs. In this study of the complete tongue of an adult male giant panda, we describe the morphology of its lingual surface, the different types of papillae, their characteristics and topographic distribution. It was seen that there are four main types of lingual papillae: filiform, conical, fungiform and vallate. There was no sign of foliate papillae, tuberculum intermolare or sublingua. Papilla distribution was not limited to the dorsum of the tongue, but was also seen on the anterior and ventral surfaces of the tongue. In the anterior third of the midline there is a smooth area with no papillae at all. Morphology of the microgrooves and pores is similar to that observed in other mammals. The papillae share characteristics encountered in Carnivora and herbivorous species of mammals. A narrow bamboo-based diet and specialized manner of eating have together resulted in modification of the tongue of a carnivoran, giving it some characteristics typical of an herbivore. [source]

Phenotypic plasticity of anuran larvae: environmental variables influence body shape and oral morphology in Rana temporaria tadpoles

JOURNAL OF ZOOLOGY, Issue 2 2002
Miguel Vences
Abstract Environmental variables shaped the morphology of tadpoles of the common frog, Rana temporaria, in various ways at the Pyrenean locality Circo de Piedrafita. Examining only specimens in similar developmental stages, those from small ponds (with higher temperature and higher tadpole density) had lower growth rates, lower relative tail height, lower relative body width and fewer labial keratodonts and keratodont rows. The variation in keratodonts may have been caused by heterochrony related to the slower growth rate. The number of lingual papillae also differed between ponds but was not related to pond size. Higher predator densities caused a higher percentage of damaged tails and a lower relative tail length in specimens with apparently intact tails, probably as a result of incomplete regeneration after mutilations earlier in development.

E. J. Benetti
Summary The study of lingual surfaces and the surface of interface epithelium-connective tissue of the tongue of Bradypus torquatus was performed by employing the light and scanning electron microscopy (SEM) techniques. The results revealed that the rostral part of the tongue presents a round apex and covered by filiform and fungiform lingual papillae and a ventral smooth surface. It was observed that the epithelial layer of the dorsal surface possesses the basal, spinosum, granular and cornified epithelial cells. The lamina propria is characterized by a dense connective tissue forming the long, short and round papillae. Numerous typical filiform papillae are located especially in the rostral part intermingled for few fungiform papillae, which were revealed in three-dimensional SEM images. Usually, the fungiform papillae are located in the border of rostral apex of the tongue exhibiting the rounded form. They are covered by keratinized epithelial cells. In the fungiform papillae, several taste pores were observed on the surface. The vallate papillae presented numerous taste buds in the wall of epithelial cells, being that the major number of taste buds is located on the superior half of vallate papilla. The taste pores are surrounded by several laminae of keratinized epithelial cells. The samples treated with NaOH solution and examined by SEM revealed, after removal of the epithelial layer, the dense connective core in original disposition, presenting different sizes and shapes. The specimens stained with Picrosirius and examined by polarized light microscopy revealed the connective tissue, indicating the collagen fibres type I and type III. [source]
