Light and scanning electron microscopic study of the filiform papillae of the tongue in adult rabbit (Oryctolagus cuniculus f. domestica, Linnaeus 1758)

Abstract

Summary. This study was conducted on 10 tongues of adult rabbits (Oryctolagus cuniculus f. domestica), of both sexes (five females and five males). The filiform papillae of the tongue were studied, using light and scanning electron microscope. The filiform papillae were arranged on the dorsal surface of the apex and body of the tongue and on its margins. The investigation showed that there were single and complex filiform papillae on the rabbit tongue. These single filiform papillae were cone-shaped, similarly as their connective tissue cores. Complex papillae were palm-shaped and cone-shaped with three to seven processes. However, the number of processes towards the throat diminished. Connective tissue cores of these papillae had also processes. The filiform papillae consisted of an anterior and posterior epithelial cell column. The anterior epithelial cell column showed signs of parakeratinization or soft keratinization whereas the posterior epithelial cell column -hard keratinization. Between filiform papillae there was interpapillary epithelium which did not have any signs of keratinization.

“…Це широко розповсюджені сосочки, які покривають усю поверхню язика за винятком його кореня. Вони разом із піднебінням залучаються до проштовхування їжі у правильному фізіологічному напрямку (Iwasaki, 2002;Kobayashi et al, 2006;Masuko et al, 2007;Kulawik et al, 2015). Miyawaki et al (2010) i Abumandour (2014) ниткоподібні сосочки поділяють на власне ниткоподібні та конусоподібні.…”

“…Результати досліджень про такий розподіл сосочків язика близькі до даних авторів, які проводили їх вивчення в інших тварин (Benetti et al, 2009;Can et al, 2016). У миші, опосума, кроля та морської свинки поверхня валикоподібних потовщень тіла язика вкрита конічними сосочками (Okada et al, 2005;Kilinc et al, 2010;Kulawik et al, 2015). Присутність щіткоподібних сосочків також знайдена у летючих білок, кроля та кота (Ojima et al, 2000;Nonaka et al, 2008).…”

“…Ultrastructure study on Dasypus hybrid tongue detect taste buds carrying on fungiform and circum allate papillae that both are responsible for taste, while mechanical and protective role carry out by filiform ones [6]. At the first day after birth taste bud were observed on vallate papillae of domestic rabbit tongue [7]. Kulawik, et al, revealed that the filiform papillae are cone or palm shaped with three to seven processes in a study by light and scanning electron microscope of the filiform papillae of the tongue in adult rabbit (Oryctolagus cuniculus) [8].…”
