Background Dietary habit among vertebrates depends upon the morphological and anatomical structure of tongue.Aim We here compare between morphological, histological aspects tongue Coturnix coturnix (granivorous bird) R. aegyptiacus (fruit-eating mammal).Method Six individuals each species were used; tongues removed, photographed, processed for histological, histochemical, scanning electron micr...

Vernal keratoconjunctivitis (VKC), a severe form of ocular allergic disease, is characterized by the formation of giant papillae at the upper tarsal conjunctiva and corneal lesions that threaten vision. Recent evidence indicates that resident fibroblasts function as immune modulators in the pathogenesis of the chronic allergic inflammation associated with VKC. The T helper 2 (Th2) cell-derived ...

Transfer cell morphology is characterized by a polarized ingrowth wall comprising a uniform wall upon which wall ingrowth papillae develop at right angles into the cytoplasm. The hypothesis that positional information directing construction of wall ingrowth papillae is mediated by Ca(2+) signals generated by spatiotemporal alterations in cytosolic Ca(2+) ([Ca(2+)]cyt) of cells trans-differentia...

BACKGROUND Pain and sensory changes due to lingual nerve injury are one of the most common alterations that follow surgical removal of third molar. They are usually transient but other less common complications, such as the atrophy of fungiform papillae, have an uncertain prognosis. CASE DESCRIPTION We report a case of a 34-year-old woman who presented a unilateral lingual atrophy of fungifor...

The ability to maintain human fungiform papillae cells in culture for multiple cell cycles would be of considerable utility for characterizing the molecular, regenerative, and functional properties of these unique sensory cells. Here we describe a method for enzymatically isolating human cells from fungiform papillae obtained by biopsy and maintaining them in culture for more than 7 passages (7...

Fungiform papillae of the tongue are small projections involved in taste function that are typically located on the lateral aspects and tip of the tongue. They are called fungiform papillae because of their close resemblance to a fungus. In fair-skinned individuals, they are usually pink or red, but in dark-skinned individuals, they are frequently pigmented and are considered a variant of norma...

The papillary layer of the oral part of the human soft palate was studied in 31 subjects of different age by means of histological, immunohistochemical and scanning electron microscopical methods. For scanning electron microscopy a new maceration method was introduced. Results determine epithelial thickness, height and density of connective tissue papillae and their 3-dimensional architecture i...

Almost all ascidian larvae bear three mucus secreting and sensory organs, the adhesive papillae, at the anterior end of the trunk, which play an important role during the settlement phase. The morphology and the cellular composition of these organs varies greatly in the different species. The larvae of the Clavelina genus bear simple bulbous papillae, which are considered to have only a secreto...

BACKGROUND Gingival recession in dentitions with otherwise healthy periodontium is a common occurrence in adults. Recession is clinically measured using a periodontal probe to the nearest millimeter. The aim of this study is to establish quantitative measures of recession, the clinical crown height, and a new measure the gingival margin-papillae measurement. The latter is seen as the shortest a...

Structures associated with the rectum of insects, e.g., rectal papillae, rectal glands, rectal pads, are believed to be concerned with an active uptake of water and ions from rectal contents (1-7). In the blowfly, rectal papillae are 4 hollow cones with their tips projecting into the rectal wall and their bases facing the haemolymph. The wall of each cone is formed by a single layer of columnar...
