Gross morphological, histological and scanning electron specifications of the oropharyngeal cavity of the hooded crow (Corvus cornix pallescens)

Abstract: The present study was carried out on the oropharyngeal cavity of the hooded crow to investigate the gross and microscopic structures via gross anatomy, light microscopy and scanning electron microscopy (SEM). The gross anatomy clarified the elongated triangular shape of the oropharyngeal cavity with a non‐protruding tongue with a bifid apex. The lingual body contained median groove rostrally and separated caudally from the root by a transverse papillary crest. The laryngeal mound located posterior to the lingu… Show more

“…The tongue divided into three regions; apex, body, and root, identical to what was described in formerly published data (Abumandour, 2014a;Abumandour, 2018 Harmonious with these gross oversights, SEM imagery display that the round apex observed in all studied five developmental agestages, analogous to that noted in the goose, duck, quail and Egyptian laughing dove (Abumandour, Bassuoni, & Hanafy, 2019;Jackowiak et al, 2011;Parchami et al, 2010). The formerly published data described the presence of numerous appearance of the apex which were thought that it is correlated with the feeding style of the different feeding avian species such as; the oval apex in Hume's tawny owl (Abumandour & El-Bakary, 2017b), the pointed apex in the chicken, zebra finch and hoopoe Iwasaki & Kobayashi, 1986), the blunt apex (El-Mansi et al, 2020), the bifurcated apex note in the owl, Eurasian Hobby, house sparrow, and seagull (Abumandour, 2014a;Abumandour, 2018;Abumandour & El-Bakary, 2017b;Gewaily & Abumandour, 2020;Onuk et al, 2013).…”

“…while, they completely disappeared from the rudimentary tongue (Jackowiak et al, 2006;. These mucoid secretions are supposed to lubricate the oropharyngeal cavity and the esophagus to facilitate passage of the foods particles (El-Mansi et al, 2020;Gewaily & Abumandour, 2020).…”

“…The histological examination was adopted according to Gewaily and Abumandour [ 35 ]. The dissected intestine samples were cut into pieces of approximately 0.5 cm 3 and fixed in neutral buffered formaldehyde 10% solution for 24 h. The samples were then dehydrated in ascending grades of alcohol, cleared with xylene, and embedded in paraffin wax.…”
