The present study was conducted on tongues obtained from 10 cadavers of adult camels (Camelus dromedarius). Gross anatomical features were studied. The tongue of camel was muscular and spatula shaped, comprised of 3 parts - the apex, body and the root. The mean length of tongue was 41.21 ± 0.527 cm. A median groove was present on the dorsal surface...

Context 1
... Ye et al (2008) reported crinkled appearance of the apex of tongue on dorsal surface, but no such observations have been recorded in the present study. The presence of papillated structures on the ventral margin of the apex of tongue (Fig 2) was in congruence with the observations of Harłajczuk et al (2015) in Alpacas. A median fibrous ridge like structure "lyssa" was observed on the rostral third of the tongue at ventral surface, situated 2 -3 cm away from the tip and extended caudally to the level of frenum linguae (Figs 1 and 2) was in conformity with the findings in camels (Shoeib et al, 2014) and in dogs (Eubanks, 2007). ...
Context 2
... was in agreement with Smuts and Bezuidenhout (1987) in dromedary camel and Ye et al (2008) in Bactrian camel. These were thickly populated on the dorsal surface, in front of the fossa linguae up to the tip and moderately populated on the ventral surface of the tip (Figs 2 and 5), Similar finding were reported ( Parvez and Rahaman, 2005) in cow. No filiform papillae were found on torus linguae and root (Fig 4). ...
Context 3
... free ends of conical papillae were pointed (Fig 4). Few horny conical papillae were also found on the ventral surface of the tip (Fig 2). Parvez and Rahaman (2005) reported that the large conical papillae were located in the rostral two-thirds of the dorsum of the tongue with a higher concentration in the middle portion of the tongue in cow (Bos indicus). ...
Context 4
... ventral surface was also papillated. The filiform and fungiform papillae extended for about 5 to 6 mm beyond the tip (Fig 2). ...

... One of these adaptations is that the dromedary camel has very sturdy mouth to maintain the efficient feeding of thorny and rough-stem plants which naturally grow in the arid regions (El Sharaby et al., 2012). In addition, several studies on the mouth of camel have described the anatomical features of camel tongue (Qayyum et al., 1988;Takehana et al., 2001;Peng et al., 2008;Salehi et al., 2010;El Sharaby et al., 2012;Thanvi et al., 2020). With regards to its dorsal surface, similar to ruminants, the tongue of camel is characterized by the presence of fungiform and vallate papillae, and the lack of foliate papillae as well (Thanvi et al., 2020). ...

The present study aimed at investigating the histological structures of the vallate papillae of the tongue of the dromedary camel. Samples were taken from the tongues of 5 healthy adult dromedary camels, then processed by standard routine histological technique. The vallate papillae were broad, encircled by a distinctive sulcus, and exhibited concave dorsal surfaces. The papillae were covered with stratified squamous epithelium which was made up of several layers of cells arranged from the basement membrane to the outer surface as follows: basal layer; spinosum layer; squamous layer; corneum layer. The lamina propria sub mucosa showed two well-defined layers. The first one was located beneath the epithelium and characterized by loose connective tissue. The second layer was much thicker and composed mainly of dense irregular collagenous fibres. Deep to the circumvallate papilla was a group of prominent tubulo-acinar glands (von Ebner’s glands). The main ducts of the glands opened directly into the surrounding sulcus at different levels. In general, the histological structures of the vallate papillae of the dromedary camel were similar to those of other domestic mammals. The well-developed von Ebner’s glands suggested their abundant serous secretion that reflected on the high capability of gustation.
