Article Abstract
Background: We present a first case report of an Actinomycosis lesion of the ventral tongue. Actinomycosis of the tongue is an uncommon finding.
Case Description: The 64-year-old female patient presented with a leukoplakic ventral tongue lesion. The diagnosis Actinomycosis was confirmed by histopathologic evaluation. The lesion was successfully treated with antibiotics and laser ablation therapy.
Practical Implications: Diagnostic and therapeutic concerns are discussed. Clinicians are alerted to considering Actinomycosis within the differential diagnosis of leukoplakic tongue lesions.
Anatomically the tongue of Gallus gallus domesticus (Galliformes: Phasianidae) is distinguished into sharp rostral apex, body and root with numerous conical papillae arranged in rows in different sizes in the free portion and the root of the tongue. The epithelium covered the dorsal and ventral surfaces of the free portion and the dorsal surface of the root of the tongue. Numerous orifices of the salivary glands were scattered in the root of the tongue.
We here report on likely human-mediated, stray sightings of Dendrelaphis proarchos (Wall, 1909) in an unnatural range-Surat, Gujarat in western India. This population shows the following characters: (1) vertebral scales distinctly enlarged, larger than the dorsals of the first row; (2) 185-194 ventrals; (3) 139-142 divided subcaudals in complete tails; (4) 15 dorsal scale rows at midbody; (5) cloacal shield undivided; (6) one loreal scale; (7) three supralabials touching the eye; (8) a moderate first sublabial that touches two infralabials; (9) 11-12 temporal scales; (10) preoculars 1 or 2; (11) two or three postoculars; (12) maximum total length 1150 mm; (13) interparietal spot absent; (14) a black temporal stripe that does not starts on the postnasal or loreal but starts on the center of the eye follows postoculars (middle or second postocular) covers the majority of the temporal region and extends onto the neck; (15) a distinct, bright ventrolateral stripe bordered by one black line at the bottom; (16) dorsal interstitial color blue and (17) tongue color red with black tip. Data from a partial fragment of the mitochondrial 16S gene also reveal genetic congruence with published sequences from Sagaing and Ayeyarwady in Myanmar and Mizoram, India, further attesting the morphological conclusions.
Crocodylians have a specialized gular valve that forms a water-tight seal in their mouths, allowing them to dive while keeping their mouths open.
This study reveals that the gular valve consists of an integrated dorsal component (the dorsal gular fold) and a mobile ventral part (the tongue and hyolingual apparatus), connected by a newly identified structure called the velar chord.
The findings suggest that the tension in the velar chord changes the shape of the dorsal gular fold, affecting various behaviors like swallowing and vocalization beyond just diving.

The oral cavity is a multifunctional organ composed of structurally heterogeneous mucosal tissues that remain poorly characterized. Oral mucosal tissues are highly stratified and segmented along an epithelial-lamina propria axis. Here, we performed spatial transcriptomics (tomo-seq) on the tongue, cheeks, and palate of the adult mouse to understand the cues that maintain the oral mucosal sites.
