The present study investigated the structure of the dorsal lingual surface tongue of the toad, Bufo bufo habitat in the west of Iran. The tongue of the toad contains two types of lingual papillae; fungiform papillae and filiform papillae. The fungiform papillae are usually scattered among the filiform papillae and are believed to function in gustation and in the secretion of salivary fluid. Lig...

PURPOSE Major chemokine receptors in the giant papillae of atopic keratoconjunctivitis (AKC) have yet to be determined. We evaluated chemokine receptor genes and their ligand expressions in upper tarsal conjunctival giant papillae of AKC with atopic dermatitis and/or asthma. METHODS CC, CXC, and CX3C chemokine receptor (R) gene expression levels in giant papillae of five clinically active AKC...

Although it has been long accepted that innervation by a taste nerve is essential for maintenance of taste buds, it is not clear what role, if any, innervation plays in the morphogenesis of taste papillae and taste bud development. The following study was undertaken to determine what effects lack of sensory innervation have on the development of taste papillae and the formation of taste buds in...

During development, axons of the chorda tympani nerve navigate to fungiform papillae where they penetrate the lingual epithelium, forming a neural bud. It is not known whether or not all chorda tympani axons initially innervate fungiform papillae correctly or if mistakes are made. Using a novel approach, we quantified the accuracy with which gustatory fibers successfully innervate fungiform pap...

OBJECTIVE The aim of this study was to analyze fungiform papillae density in patients with burning mouth syndrome (BMS) and xerostomia. STUDY DESIGN In this cross-sectional clinical study, sixty patients were included (20 with BMS, 20 with xerostomia and 20 healthy controls). The fungiform papillae density was analyzed over a small region on the anterior tip of the tongue with the aid of a di...

Rice ( Oryza sativa ) is a water-intensive crop, and like other plants uses stomata to balance CO 2 uptake with water-loss. To identify agronomic traits related rice stomatal complexes, an anatomical screen of 64 Thai 100 global cultivars was undertaken. Epidermal outgrowths called papillae were identified on the subsidiary cells all cultivars. These also detected eight species genus but not an...

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...

Taste bud quantitation may provide useful parameters for interspecies comparisons of the gustatory system. The present study is a morphometric analysis of bovine taste papillae. Circumvallate and fungiform papillae from six bovine tongues were serially sectioned and, following staining, analyzed. Circumvallate papillae were found to have a mean volume of 3.66 +/- 2.82 mm3, a mean number of tast...

In the present investigation, the histological and histochemical characteristics, as well as the ultrastructure of the lingual epithelium of the adult lizard Chalcides ocellatus, were investigated by light microscopy (LM) and scanning electron microscopy (SEM). Histological examination revealed taste buds and sensory papillae on the tongue tip and on the foretongue. The papillae were covered by...

PURPOSE The purpose of this pilot study is to propose a technique, the split-finger approach, to preserve/promote papillae formation. MATERIALS AND METHODS Twenty-one patients with 39 implants consecutively placed in the maxillary anterior region were evaluated at 6 months to 1 year after prosthodontic restoration. The implants evaluated included 16 single-tooth implants, 1 2-unit implant pro...
