Abstract

This study aimed to provide a full morphological description of the oropharyngeal cavity in the domestic geese with gross examination, morphometric analysis and scanning electron microscopy. Eight heads of adult healthy geese were used in this study. The oropharyngeal roof had a large rostral part with five palatine ridges; one median, two paramedian and two lateral longitudinal rows of blunt tubercles bounded laterally by transverse horny lamellae of the beak. The caudal papillary region exhibited choanal and infundibular clefts, surrounded by caudally directed conical papillae. In floor, an elongated tongue had a rounded apex with lingual nail and carried filiform papillae on its lateral edges. Each side of the lingual body carried 9 small conical papillae on the anterior part and 6 giant conical papillae on middle and posterior parts. These conical papillae were distributed among the filiform and hair-like papillae. The Posterior part of lingual body was thickened forming the lingual prominence with a transverse row of caudally directed 8-10 conical papillae forming a papillary crest. Lingual root consisted of a triangular surface surrounded by spinated borders. Caudally, an ovoid laryngeal mound with glottis is located in the pharyngeal floor, with conical papillae on its borders and transverse rows of large-sized pharyngeal papillae arranged linearly as 4-5 papillae on posterior part of the laryngeal mound. Openings of the salivary glands were observed in their corresponding region. In conclusion, the morphological characteristics of the oropharyngeal structures in geese confirmed their adaptation to the feeding habits and type of available food particles.
