They are predominant on the apex and generally are inclined at the caudal region, whereas they are modified and presented various shapes at the root [ 7 ].
Differences in the morphology of filiform papillae may be observed on the apex and in the middle region of tongues of several species. The conical papillae are elongated shaped with a wide base and flat apex. Their lining consists of well-developed keratinized stratified epithelial tissues with abrasion and protection as their main role [ 8 ].
The fungiform papillae may be identified on the apex, featuring a great quantity of connective tissues and adjacent epithelial layer.
The foliate papillae when present are situated at the bilateral margins of the caudal region, are leaf-shaped structures, separated from one another by an invagination of the mucous membrane, and have taste buds. The amount of foliate papillae may vary according to the evolution of each species [ 10 ].
The vallate papilla is the biggest of the papillae and is situated on the caudal region of the dorsal surface, involved in a deep continuous groove.
The quantity and shape of the vallate papillae vary widely and depend on the species analyzed [ 11 ].
They vary in size and shape, from round shaped to flat shaped, either lying parallel or in rows at each side of the caudal region. Groups of glands, also known as von Ebner glands, are detected in the lower part of the vallate papillae. They are salivary serous glands where ducts open at the base of the papillae grooves and secrete a watery liquid that dissolves food contents and makes easy taste perception [ 12 ].
In the order Rodentia, several studies have been undertaken on mice [ 13 , 14 ], cavy [ 15 ], agouti [ 12 ], flying squirrel [ 16 ], American beaver [ 17 ], and lowland paca [ 7 ]. However, studying the lingual papillae of rats may note different shapes on the surface and their connective tissue cores CTCs in the treated samples with NaOH solution.
The types and subtypes of tongue's papillae of rodent mammals may exhibit several differences in the morphological characteristics to classification, shape, and taste buds. The aim of the present study was to describe the three-dimensional morphological characteristics of the lingual papillae and their connective tissue cores CTCs of Sprague Dawley rats employing scanning electron microscope methods.
Material and Methods Four tongues of four-month-old male rats, species, order: Rodentia, were investigated. The samples were then washed in a buffer solution and divided for the different techniques. Conventional technique comprised the washing of samples in distilled water for 2 hours at room temperature to analyze the epithelium surface.
After this stage, all samples were dehydrated in an increasing series of alcohols and dried in a critical point dryer Balzers CPD with liquid CO2.
Results The analyses by scanning electron microscope showed that filiform papillae were the most numerous on the dorsal surface of the tongue with a decreased amount on the caudal region. They are shaped and have different diameters according to the region.
In the rostral region the papillae are low cone shaped, with a rounded apex Figure 1 a. Elongated and multifilamentary papillae may be found in the middle and caudal regions, with their respective long and thin filaments Figure 1 c.
After the removal of the epithelium, the CTCs of the filiform papillae rostral region revealed low, with a cone-shaped apex, a base wider than the apex, and thin bundles in the interpapillae zone Figure 1 b , different from other filiform papillae.
A greater magnification revealed three to four filaments multifilamentary starting from the third mid-upper part of the CTCs Figure 1 d. Fungiform papillae were distributed in the rostral and middle regions of the dorsal surface. They are very numerous in the rostral region, with a rounded shape and dome-like top.
In the details one may note that the papillae surface comprises a squamous epithelium and a taste orifice on the top of the surface Figure 1 e. More like this Similar Items.
