Sažetak
Cilj ove studije je bio da se elektronskkom mikroskopijom opišu distribucija i struktura površine lingvalnog papilarnog sistema kod četiri odrasla pastuva rase engleski punokrvnjak. Životinje je obezbedio 'Jockey Club of Turkey (TJK)'.Uzorci tkiva uzeti su sa dorzalne, ventralne i lateralne površine vrha, tela i korena jezika. Filiformne papile su bile raspoređene prvenstveno dorzalno. Bile su brojne, dugačke, tankog i cilindričnog oblika, šilatog vrha ili sa višestrukim račvama na apeksu. Ove papile su tipično bile konusnog oblika sa širom osnovom na telu jezika, dok su bile odsutne sa korena jezika. Pečurkaste papile su uočene na lateralnim delovima gde su uočeni i lobulaarni oblici. Konji poseduju i dve opšančene papile smeštene na dorzumu bliže kaudalnom delu jezika. Ove papile su okružene uočljivim gustativnim šancem. Opšančene papile poseduju mnogobrojne pore u papilarnom šancu. Listaste papile su uočene rostralno u odnosu na palatoglosalne lukove. Ove papile poseduju pore različitih veličina čiji su otvori između listova papila. Papilarni listovi su pokriveni koncentrično aranžiranim kornifikovanim ćelijama varijabilnog izgleda. Nije zabeleženo prisustvo papila na ventralnoj strani jezika konja.
Abstract
The purpose of this study was to describe the distribution and surface structure of the lingual papillary system in four male adult English horses by scanning electron microscopy. The animals were supplied from the Jockey Club of Turkey (TJK). Tissue samples were taken from the dorsal, ventral and lateral surface of the apex, corpus and radix of the tongue. Filiform papillae were distributed mainly on the dorsum, being abundant, very long and with a slim cylindrical form with pointed endings or multi-bifurcated terminations at the apex. These papillae were typically conical in shape with a wider base in the corpus of the lingua and absent on the radix of the lingua. Fungiform papillae were mainly on the lateral surfaces and lobulated forms were also observed. The horses have two large vallate papillae, located on the dorsum close to the caudal part of the tongue. These papillae were surrounded by a prominent gustatory groove. The vallate papillae had many taste pores opening into the papillary groove. The foliate papillae were observed just rostral to the palatoglossal arches. These papillae have many variable sized taste pores which open into the grooves between the papillary leaves. The papillary leaves were covered with concentrically arranged cornified cells of variable appearance. However, there were no lingual papillae on the ventral aspect of the horse's tongue.
