The microstructure of lingual papillae on the dorsal surface of the tongue of adult Egyptian fruit bats was examined by light microscopy (LM) and scanning electron microscopy (SEM). This elongated tongue with a rounded apex is approximately 3 cm long -- including the 1.7cm length of the anterior free part of the tongue -- which facilitates considerable freedom of movement. The surface of the to...

This paper presents a comparison of the morphological structure of the filiform papillae in New Zealand white rabbits as domestic mammals and Egyptian fruit bats as wild mammals. This study was carried out on the tongues of adult healthy New Zealand white rabbits and Egyptian fruit bats of both sexes. There were four types of lingual papillae in both animals. In the Egyptian fruit bats, there w...

Cephalopods can reversibly change their appearance by expressing papillae – folds, bumps, spikes, or even more complex structures – on their skin for camouflage purposes. This project, in collaboration with Dr. Roger Hanlon, Marine Biological Laboratory, sought to examine the biomechanics of papillae formation, develop methods to simulate papillae formation, and develop biomimetic artificial pa...

We used an embryological approach to investigate development and microvasculature of lingual papillae, and expression of vascular endothelial growth factor (VEGF) in the rat tongue. Temporal changes in the rat tongue at each developmental stage from embryonic day 13 (E13) to postnatal day 7 (P7) were observed by intravascular injection of India ink and immunohistochemistry using a VEGF antibody...

A pronounced species variation in the organization of filiform papillae has been observed. Preliminary histologic studies of cat tongue revealed marked regional variations in size, shape and organization of filiform papillae. Therefore, a correlated light microscopic, transmission and scanning electron microscopic study of tissue samples of representative areas of the cat tongue was undertaken ...

Lingual papillae of wild boar and pig were studied by means of scanning electron microscopy (SEM). Vallate papillae appear with the typical circumvallate morphology. Their papillary bodies show conical or fungiform-like and spicule-like pseudopapillae in both animals. Taste pores were seen in the papillary grooves. Microplicae or pits are visible at high magnification. In pig and wild boar simi...

The external morphology of the papillae linguales (papillae filiformes, papillae fungiformes and papillae vallatae) and their connective tissue cores (CTCs) of the greater Japanese shrew-mole (Urotrichus talpoides) were analysed by optical and scanning electron microscopy. Papillae filiformes were distributed over the dorsal surface of the apex linguae, and on the rostral and caudal regions of ...

A detailed description of cibarium of Armigeres (Armigeres) subalbatus (Coquillett) has been illustrated for the first time with the aid of Scanning Electron Microscope. The description of cibarial armature is based on structure of cibarial bar, width & characteristic of lateral flanges and number of cibarial sense organs or papillae viz. palatal papillae, larger dorsal papillae, and smaller do...
