“…According to Stadtmuller ('38), the tongue of Myomorpha belongs to the first type, Leoporidae, Hystricidae, Erethizontidae and Spalacidae to the second and Sciuridae, Castoridae, Lagomyidae, Nesomyidae, Dipodidae, Cricetomys and Ctenodactylus to the third. It has been accepted that the triangular arrangement of three vallate papillae in the third type is the most primitive pattern of the mammalian tongue (Honigschmied, 1872;Tuckerman, 1891;Munch, 1896;Oppel, '00;Sonntag, '24-'25;Stadtmuller, '38). Hence, it can be said that among Lagomorpha the pika's tongue with three vallate papillae is more primitive than that of Lepus having two papillae.…”

The tongue of the Japanese pika was investigated usjng the silver impregnation method. On the dorsum, three vallate papillae, arranged in a row transversely, and foliate papillae with 12-13 clefts were observed. The papillae are both covered with a n upper thickened epithelium. The abundant ne:cve fibers are widely distributed in the subpapillary layer of the lamina propria to form the subpapillary nerve plexus, which is composed of non-myelinated and thick myelinated fibers, and ganglion cells. The taste buds, of an embryonic type with an indefinite border, are located as a mass in both walls of the papillae symmetiically, closely associated with a small number of the fine fibers from the subpapillary plexus. They are large in size and penetrate into the subgemmal connective tissue. Their aspect suggests a peculiar receptive apparatus surrounding the orifice of the serous gland-ducts. In the papilla regions the serous glands are plentiful deep in the muscles and their ducts open into the bottom of the trench and furrow. The dorsum is densely packed only with the filiform papillae which are covered with highly cornifi.ed, thickened stratified squamous epithelium and poor in nerve supply, but the smooth inferior surface is well supplied with sensory nerves ending free and is furnished with many taste buds. No apical glands are present. The tongue contains many ganglion cells alongside the nerve fiber bundles running toward the apex.

“…From descriptions of previous workers (Martin, 1836;Owen, 1836Owen, , 1852Mayer, 1844;Flower, 1872;Honigschmied, 1873;Young, 1881;Poulton, 1833a, b;Tuckerman, 1889aTuckerman, , b, 1890Tuckerman, , 1891Tuckerman, , 1892Munch, 1896;Parsons, 1896;Windle and Parsons, 1898;Oppel, '00;Sonntag, '24, '25;Stadtmuller, '38), it is obvious that the tongue of marsupials has three circumvallate papillae arranged in an inverted V-shape. However, there are some differences between their structures; the anterior papilla is much larger than the posterior.…”

“…The tongue of the marsupials has been extensively investigated (Martin, 1836;Owen, 1836Owen, , 1852Mayer, 1844;Flower, 1872;Honigschmied, 1873;Young, 1881;Poulton, 1883a, b;Tuckerman, 1889aTuckerman, , b, 1890Tuckerman, , 1891Tuckerman, , 1892Munch, 1896;Parsons, 1896;Windle and Parsons, 1898;Oppel, '00;Sonntag, '24, '25;Stadtmuller, '38). The data reported by these investigators may be summarized as follows: ( 1 ) Three circumvallate papillae are arranged i n an inverted V-shape.…”

Macroscopic and neurohistological observations of the red, gray and tree kangaroo and wombat's tongues are described. On the dorsum, three circumvallate papillae, foliate papillae (gland-duct type), fungiform papillae and filiform papillae are observed. In the wombat, the vallate papillae are shaped like a "lotusnut." Its summit is broadened, rough, and reaches the level of the dorsal surface, The papillae of the kangaroo are shaped like a "walnut" and are situated below the dorsal surface of the tongue. The vallate papilla is occupied with abundant nerves, thin non-myelinated and thick myelinated fibers, and ganglion cells, multipolar and unipolar. In the upper area of the wombat's papilla, however, there is a demarcated thin layer of non-innervated connective tissue. Therefore, taste buds are located in nearly the whole wall of the papilla in the kangaroo, but only in the lateral wall in the wombat, closely associated with the subgemmal nerve plexus. Foliate papillae

“…Rabbit tongues have been useful for morphological studies. The majority of studies, however, have been restricted to epithelial cells or to the gustatory epithelium, particularly the taste buds of well-developed foliate papillae (Tuckerman, 1890; Omar Trujillo-Cenoz, 1957; Scalzi, 1967;Toyoshima and Shimamura, 1981;Liu and Lee, 1982;Iwasaki, 1987;Kobayashi, 1992). Stereo structure of both the lingual papillae and their CTC of rabbits is provided by Silva et al (2002), but more detailed study has been demonstrated herein.…”

Summary:The morphological structure of the lingual papillae and their connective tissue cores (CTC) in a rabbit were studied using LM and SEM and were compared to that of other animal species. Externally, the filiform papillae distributed on the anterior surface of the dorsal tongue were short and conical with a round base and had a flat area on their anterior upper half. The CTC of the conical filiform papillae had a roughly triangular plate-like structure with a round top. Several small round protrusions were found on both inclined planes of the triangle. Spearhead-like filiform papillae were distributed on the anterior edge of the lingual prominence and branched filiform papillae were on the posteriorly wide area of the prominence. These papillae on the prominence had a slightly ramified CTC that differed from that of the CTC of the conical filiform papillae distributed on the anterior tongue. Dome-like fungiform papillae were distributed among the conical filiform papillae of the anterior tongue and had a CTC with a roundish structure that was almost but, not quite spherical in appearance with 1 to 10 small round concave indentations for taste buds on their upper surface. The foliate papillae had approximately 15 parallel ridges separated by grooves. These ridges contained a parallel thin plate-like CTC exhibited after removal of the epithelium. The vallate papilla was comprised of a spherical central papilla and had a circular wall with a flower-like CTC almost resembling a carnation.The stereostructure of the rabbit's filiform CTC are comparatively described as being morphologically in between those of rodents and those of the guinea pig and Japanese serow. Such evolution has probably occurred due to the species unique masticatory and gustatory needs and functions.
